How do I hire an executive assistant to support me as Chief of Staff?

Hiring an executive assistant (EA) to support you in your role as a Chief of Staff (CoS) is a strategic move. A great EA-CoS partnership forms a powerful command center, allowing you to focus on high-level strategy while they protect your operational blind spots.

Here is a step-by-step framework to hire the right person for this critical leverage role:

• Role Breakdown: Map out your own responsibilities as CoS. Identify which tasks are transactional (calendar management, travel booking, expense reports) versus operational (project coordination, internal comms, meeting prep). Your EA should absorb the heavy lifting of the former and support you on the latter.

• Competency Profile: Look for high EQ (emotional intelligence), radical discretion, exceptional anticipation (thinking three steps ahead), and a bias for action.

• Positioning: Frame the role clearly. They aren't just supporting an executive; they are supporting the Chief of Staff to run an efficient organization.

• Core Responsibilities: Detail calendar and inbox management, gatekeeping, cross-functional coordination, and handling confidential information.

• Cultural Fit: Emphasize that they must thrive in a fast-paced, high-context environment where ambiguity is the norm.

• Specialized Networks: Leverage executive assistant communities and specialized recruiting agencies that vet top-tier talent. Check out platforms like EAtoCoS resources via the Chief of Staff Network for peer insights.

• Referral Networks: Tap into executive assistant networks on LinkedIn or specialized fractional/remote EA platforms (such as Athena, Boldly, or EA-specific boutique recruiters).

• The Resume Screen: Look for longevity in previous roles, evidence of complex project management, and experience supporting high-capacity leaders.

• The Initial Phone Screen: Test for communication style, baseline professionalism, and cultural alignment.

• The Practical Assessment: Give them a realistic scenario test. For example: "Here is a chaotic, double-booked calendar and a messy inbox with conflicting priorities. How do you triage this in 15 minutes?" This tests prioritization and calmness under pressure.

• The Final Interview: Involve a key stakeholder or peer to see how they interact with someone outside the direct reporting line.

• Context Sharing: Don't just hand over a task list; share the "why" behind your priorities, company politics, and executive communication styles.

• The First 30 Days: Establish clear communication cadences (daily syncs) and gradually transition ownership of the calendar and inbox once trust is established.

To help tailor this, would you like me to:

• Draft a custom job description template for this specific reporting structure?
• Provide a list of interview questions designed to test anticipation and EQ?

Hiring an executive assistant (EA) to support you as a Chief of Staff is a little different from hiring an EA for a CEO or executive directly. Your EA should not just “manage your calendar”; they should become the operating backbone that protects your time, improves your execution rhythm, and allows you to spend more time on strategic work. The key is to define the role clearly so it complements your Chief of Staff responsibilities rather than duplicating them.

1. Define what you actually need them to own

Before writing a job description, list the recurring friction you want removed.

A strong EA supporting a Chief of Staff might own:

• Calendar architecture

• Protecting focus time

• Preparing you for key meetings

• Resolving scheduling conflicts using judgment

• Managing recurring leadership rhythms

• Meeting operations

• Agenda collection

• Pre-read coordination

• Notes and action-item tracking

• Follow-up reminders

• Information flow

• Inbox triage

• Drafting responses

• Surfacing priorities

• Maintaining key documents

• Stakeholder coordination

• Internal and external scheduling

• Executive relationships

• Partner communications

• Operational leverage

• Travel

• Expense management

• Event logistics

• Vendor coordination

• Special projects

Your Chief of Staff should typically remain focused on strategy, alignment, decision support, and cross-functional execution—not become consumed by administrative mechanics.

2. Decide the level of EA you need

Common profiles:

Administrative Executive Assistant

Best if you mainly need:

• Calendar management
• Travel
• Expenses
• Basic coordination

Executive Business Partner (often the sweet spot)

Best if you need:

• Independent judgment
• Proactive problem-solving
• Meeting preparation
• Executive communication support
• Project ownership

EA + Operations hybrid

Best if your environment is fast-moving and ambiguous:

• Runs operating cadences
• Tracks commitments
• Builds systems
• Coordinates leadership workflows

For a Chief of Staff, I would usually bias toward an Executive Business Partner profile rather than a traditional administrative EA.

3. Write the job description around outcomes, not tasks

Avoid:

“Looking for someone to manage calendar and scheduling.” Use something like:

“Partner with the Chief of Staff to increase executive leverage by managing operating rhythms, protecting priorities, improving information flow, and ensuring critical commitments move forward.” Example success metrics:

First 90 days

• Calendar is optimized around priorities
• Meeting preparation process is standardized
• Leadership follow-ups have clear ownership
• Inbox workflow is established
• Key stakeholder preferences are documented

After 6 months

• Executive time is consistently focused on highest-value activities
• Recurring operating processes run smoothly without intervention
• EA anticipates needs rather than waiting for requests

4. Look for these traits

The best candidates usually demonstrate:

• Judgment: knows what requires escalation vs. handling independently
• Discretion: comfortable with confidential information
• Anticipation: sees problems before they happen
• Written communication: can represent you professionally
• Calm under pressure: handles changing priorities
• Operational rigor: has systems, not just good intentions

A great EA is often less about administrative speed and more about trust, prioritization, and judgment.

5. Use a practical interview process

I’d recommend:

Round 1: Experience + judgment

Ask:

• “Tell me about the executive you supported and how you made them more effective.”
• “What decisions did you make without asking permission?”
• “Describe a time you caught a problem before your executive noticed it.”

Round 2: Working exercise

Give them a realistic scenario:

“You have three leadership meetings, a board prep deadline, a travel disruption, and a CEO request that conflicts with a team commitment. How do you prioritize?” Evaluate their thinking, not the “correct” answer.

Round 3: Writing test

Ask them to:

• Draft an executive email
• Turn messy notes into action items
• Create a meeting agenda

Round 4: References

Ask former executives:

• “Would you hire this person again?”
• “What did they handle without you knowing?”
• “Where did they require more direction?”

6. Where to source candidates

Good places:

• Your executive network
• Referrals from other Chiefs of Staff
• Former EAs from high-performing executives
• Executive support communities
• Specialized recruiters

For senior EA roles, referrals are especially valuable because trust and working style matter so much.

7. Avoid these hiring mistakes

• Hiring someone too junior because “it’s just scheduling”
• Hiring someone who needs every decision approved
• Expecting an EA to become a Chief of Staff
• Giving them responsibility without access or authority
• Not explaining your working style

The most successful partnerships are built when the EA understands: “My job is to make my executive more effective.”

A sample profile I would hire for your situation

Title: Executive Business Partner to Chief of Staff

Reports to: Chief of Staff

Mission: Increase the Chief of Staff’s leverage by managing executive operations, strengthening communication flow, and ensuring priorities move from decision to execution.

Ideal background:

• 5–10 years supporting senior executives
• Experience in high-growth, consulting, finance, technology, government, or complex organizations
• Strong project management instincts
• Excellent written communication
• Comfortable operating with ambiguity

If you are the Chief of Staff at a startup, large company, nonprofit, or government organization, the ideal profile and compensation range can differ significantly. I can help tailor the role description and interview scorecard to your environment.

• Excellent written communication
• Comfortable operating with ambiguity

If you are the Chief of Staff at a startup, large company, nonprofit, or government organization, the ideal profile and compensation range can differ significantly. I can help tailor the role description and interview scorecard to your environment.

If you mean “I’m already the Chief of Staff, and I want an Executive Assistant who makes me dramatically more effective,” I’d hire for a high-trust, operator-level EA, not a conventional administrative assistant.

The key is to design the role around leverage, rather than simply dumping tasks on someone.

1. Define what you actually want off your plate

Before recruiting, look at your last 2–3 weeks and categorize your work:

• Calendar & time: scheduling, rescheduling, protecting focus time, meeting prioritization
• Communication: inbox triage, drafting responses, follow-ups, reminders
• Meeting execution: agendas, briefing materials, notes, action-item tracking
• Project coordination: chasing owners, maintaining project trackers, deadlines
• Information management: preparing you for meetings, finding documents/context
• Travel & logistics: itineraries, expenses, events
• Personal/admin: only if you want this included

For a CoS, I'd aim for the EA to own the operational layer around you, while you retain the higher-order judgment, strategy, and relationship work. That's consistent with the distinction between EA and CoS: the EA protects the executive's time and operating system; the CoS typically works further into organizational priorities and strategy.

A useful test is:

“What am I doing repeatedly that someone with good judgment could do 80–90% as well as me?” That's your EA's territory.

2. Hire for judgment, not typing speed

For someone supporting a Chief of Staff, I'd prioritize these traits:

1. Exceptional judgment — knows what needs your attention and what doesn't.
2. Proactivity — notices problems before you do.
3. Follow-through — doesn't require you to remind them.
4. Discretion — comfortable handling sensitive information.
5. Organizational intelligence — understands who matters, how decisions get made, and when to push.
6. Written communication — can draft things that sound like you.
7. Calm under pressure — doesn't transmit chaos back to you.
8. Systems thinking — builds repeatable workflows instead of becoming the workflow.
9. Technological fluency — comfortable with your calendar, email, docs, project-management tools and AI.
10. Low ego — willing to do invisible work exceptionally well.

The best candidate may have the title Executive Assistant, but I'd look for someone who has already operated as a senior EA, executive partner, business coordinator, or operations lead. High-level CoS guidance similarly emphasizes trust, follow-through, organizational savvy and the ability to operate with considerable autonomy.

3. Give them real ownership

I'd structure the job around outcomes, not a list of 40 tasks.

For example:

Outcome 1: My calendar reflects my priorities. They own scheduling, prioritization, meeting hygiene, buffers and protecting focus time.

Outcome 2: Nothing important falls through the cracks. They maintain your commitments, follow-ups and action items and proactively surface overdue items.

Outcome 3: I'm prepared for every important interaction. They ensure you have the right context, documents, people and objectives before meetings.

Outcome 4: Communication flows efficiently. They triage your inbox/messages, draft responses and escalate only what genuinely requires you.

Outcome 5: My operating system gets better over time. They continually improve processes rather than simply performing them.

That's much more powerful than “manage calendar and travel.”

4. Don't accidentally hire a junior CoS

This is particularly important in your case.

You probably don't want an EA who thinks their job is to become your second Chief of Staff. And you don't want a CoS-level person who becomes frustrated because 60% of their day is scheduling.

A useful division is:

a16z explicitly cautions against making a CoS primarily an EA, noting that if administrative/personal work dominates the role, an EA is probably what you need.

5. Use a practical hiring process

I'd do four stages.

Stage 1: 30-minute screen

Look for evidence of autonomy.

Ask:

• “Tell me about the most demanding executive you've supported.”
• “What did you own without being asked?”
• “Tell me about a time you prevented a problem before your executive knew about it.”
• “How did you decide what to escalate?”
• “What would your previous executive say they never had to worry about because of you?”
• “Tell me about a system you built that made an executive more effective.”

The last question is particularly revealing.

Stage 2: References

Don't just ask whether they're “great.”

Ask the former executive:

“If you could hire this person again tomorrow, what would you trust them with immediately?” Then:

“What did you still have to manage yourself?” And:

“What kind of executive would this person not work well with?” That last question can uncover fit issues quickly.

Stage 3: Paid working exercise

This is probably the most valuable part.

Give candidates a fictionalized version of your actual environment:

Here are 15 emails, 8 meeting requests, 5 competing priorities, a messy calendar and three urgent requests.

Show me how you would organize my next two days, what you'd handle yourself, what you'd escalate, and what you'd push back on. Then give them a second exercise:

“I have an important meeting tomorrow with X. Prepare me.” You're testing judgment, not formatting.

Stage 4: Working session with you

Have the finalist spend 60–90 minutes with you.

Give them permission to ask questions and challenge assumptions.

You want to see whether they naturally say things like:

“Why are you attending this meeting?” or

“Could we move these three meetings together and preserve Friday afternoon?” rather than:

“What time would you like me to schedule this?” That's the difference between an assistant who processes requests and an executive partner who creates leverage.

6. Make the first 90 days explicit

Don't expect them to magically understand your brain.

For the first few weeks, give them unusually high exposure to how you work. SHRM recommends substantial CEO/CoS interaction during the early period, including shadowing and regular check-ins; the same principle applies strongly to an EA supporting a CoS.

I'd structure it:

Days 1–30: Learn

• Your priorities
• Your calendar philosophy
• Key people
• Communication preferences
• Decision/escalation rules
• Tools and systems

Days 31–60: Own

• Calendar
• Inbox triage
• Meeting preparation
• Follow-ups
• Travel/logistics
• Recurring workflows

Days 61–90: Improve

• Identify friction
• Automate repetitive work
• Redesign workflows
• Anticipate needs
• Reduce the amount of information you personally have to process

By day 90, the goal should be that you can't imagine going back to your old operating model.

7. Measure the hire by leverage

Don't evaluate them on “how busy” they are.

Track things like:

• Hours/week of your time reclaimed
• % of meetings you enter fully prepared
• % of commitments followed up without your intervention
• Number of recurring processes automated/improved
• Response time on important requests
• Number of things they proactively identify
• Reduction in scheduling/context-switching overhead

A good EA should make you less administratively busy and more cognitively available.

My ideal profile for your situation

I'd probably advertise the role as something like:

Executive Assistant to Chief of Staff — High-Trust Executive Partner

And I'd target someone with 5–10+ years of experience, including meaningful experience supporting a founder, CEO, C-suite executive, investor, or senior operator.

I would not over-index on a bachelor's degree, prestigious company names, or a particular software stack. I'd care much more about whether the person has repeatedly demonstrated:

“Give me an ambiguous mess and I'll quietly turn it into a functioning system.” That's the person I'd want beside a Chief of Staff.

If you tell me your company size, what your CoS role encompasses, and what you currently spend most of your time doing, I can help you design the exact EA profile, compensation level, interview scorecard, and a 30/60/90-day plan.

Have the finalist spend 60–90 minutes with you.

Give them permission to ask questions and challenge assumptions.

You want to see whether they naturally say things like:

“Why are you attending this meeting?” or

“Could we move these three meetings together and preserve Friday afternoon?” rather than:

“What time would you like me to schedule this?” That's the difference between an assistant who processes requests and an executive partner who creates leverage.

6. Make the first 90 days explicit

Don't expect them to magically understand your brain.

For the first few weeks, give them unusually high exposure to how you work. SHRM recommends substantial CEO/CoS interaction during the early period, including shadowing and regular check-ins; the same principle applies strongly to an EA supporting a CoS.

I'd structure it:

Days 1–30: Learn

• Your priorities
• Your calendar philosophy
• Key people
• Communication preferences
• Decision/escalation rules
• Tools and systems

Days 31–60: Own

Hiring an executive assistant (EA) to act as your right hand while you serve as Chief of Staff is one of the highest-leverage moves you can make. It frees you up to focus on strategic initiatives, cross-functional leadership, and high-level execution.

Here is a step-by-step roadmap to finding, hiring, and onboarding the right partner:

• Define the Scope and Support Model : Determine whether you need a dedicated 1:1 EA or someone who splits time. Clarify the split between tactical support (calendar management, travel, inbox triage) and elevated responsibilities (project management, internal communications, meeting prep).
• Build a Compelling Scorecard : Rather than just a standard job description, outline the core outcomes for the first 90 days. Focus on behavioral traits like extreme ownership, high EQ, anticipation, and radical discretion.
• Source Strategically:
  • Tap into specialized EA networks and communities like The Assist or EA Office Hours.
  • Leverage boutique search firms that specialize in administrative and executive talent if you have the budget.
• Design a Rigorous Interview Process:
  • Screen for communication skills and attention to detail from the very first interaction.
  • Conduct a practical working test (e.g., managing a messy mock calendar with conflicting VIP requests or drafting an ambiguous follow-up email).
• Onboard for Partnership, Not Just Tasks : Set clear operational rhythms from day one. Establish communication preferences, a shared "source of truth" for priorities, and a feedback loop to build trust quickly.

Would you like me to help you draft a job description/scorecard or design a practical work test for the interview process?

If you’re already a Chief of Staff, I’d hire an operator-grade Executive Assistant, not a traditional administrative assistant. The goal is to make you dramatically more effective by taking ownership of the coordination and logistics around your work, while you stay focused on strategy, decision-making, and cross-functional execution.

The distinction matters: an EA should optimize your time and information flow; you should be optimizing the executive’s leverage and the organization’s priorities.

1. Design the role around outcomes

I’d make the EA responsible for five things:

• Calendar architecture: Build and continuously optimize your calendar around priorities, protecting focus time and preventing unnecessary meetings.
• Meeting operating system: Prepare agendas/materials, capture decisions, track action items, and make sure follow-ups happen.
• Inbox & communications: Triage your inbox/Slack, draft responses, escalate only what genuinely requires you, and maintain your voice.
• Logistics: Travel, expenses, offsites, leadership meetings, vendors, scheduling, and the inevitable details that otherwise consume your attention.
• Chief-of-Staff leverage: Maintain your task/project dashboard, chase dependencies, prepare you for important meetings, and keep your commitments from falling through the cracks.

That last category is the differentiator. A good EA doesn't merely do things you ask them to do; they learn your priorities well enough to anticipate what needs to happen next. Modern EA descriptions emphasize calendar ownership, communications, travel, confidentiality, liaison work, and project coordination.

2. Look for this profile

I'd prioritize judgment over years of experience.

Your ideal person is:

• Extremely organized without being rigid
• Proactive—"I noticed X, so I already did Y"
• Comfortable telling you no
• An excellent writer
• Calm when everything changes at once
• Discreet and trustworthy
• Comfortable around senior executives
• Able to distinguish urgent from important
• Strong with Google Workspace/Office, Slack, calendar systems, project-management tools, and AI
• Comfortable making decisions within clearly defined boundaries
• A natural "closer" who doesn't need to be reminded about commitments

The killer trait is anticipation.

You want someone who sees:

"The CEO meeting is Thursday, the deck isn't final, three people owe us data, and the executive is traveling Wednesday." …and thinks:

"I'll get the data Tuesday, coordinate the deck, put a briefing packet on their desk Wednesday, and flag the two decisions they need to make." rather than:

"What would you like me to do?"

3. Don't hire for the title—hire for evidence

I'd avoid requiring a particular degree or industry background unless there's a genuine reason.

Instead, ask candidates for examples of situations where they:

1. Took an ambiguous responsibility and built a system around it.
2. Managed an executive's competing priorities.
3. Had to push back on a senior person.
4. Caught an important problem before their boss knew about it.
5. Managed confidential information.
6. Coordinated 10+ people who didn't report to them.
7. Recovered from a major scheduling/logistics failure.
8. Had to make a decision without being able to reach their executive.

This is much more revealing than "How organized are you?"

4. Give them a practical test

I would absolutely use a work sample.

Give the finalist something like:

"Here is my calendar for next week, a list of meetings, 15 unread emails, five outstanding commitments, and my priorities for the quarter. You have 90 minutes. Tell me what you would change, what you would delegate, what you would flag to me, and what you would handle yourself." Don't care whether they produce the "correct" calendar.

Watch how they think.

Then give them a second exercise:

"I need to prepare for a 45-minute meeting with our CEO tomorrow. Here's the background. Create the briefing I should have going into the meeting." You're testing synthesis, judgment, writing, prioritization, and anticipation simultaneously.

5. Write the job description like this

Executive Assistant to Chief of Staff

About the role

We are looking for an exceptionally organized, proactive, high-judgment Executive Assistant to partner directly with our Chief of Staff.

This person will operate as the Chief of Staff's force multiplier—owning the systems, coordination, communication, and logistics that allow the Chief of Staff to focus on the highest-leverage work across the organization.

You will:

• Own and optimize the Chief of Staff's calendar
• Manage meeting preparation, agendas, notes, decisions, and follow-ups
• Triage email and internal communications
• Coordinate complex internal and external meetings
• Manage travel, expenses, events, and offsites
• Maintain visibility into commitments, deadlines, and follow-ups
• Coordinate cross-functional projects and ensure owners follow through
• Prepare briefing materials and research for important meetings
• Anticipate needs and resolve issues before they become problems
• Serve as a trusted liaison between the Chief of Staff, executive leadership, employees, and external partners
• Handle highly confidential information with exceptional discretion
• Continuously improve the systems through which the Chief of Staff operates

You are successful when:

• The Chief of Staff rarely has to remember logistics
• Important commitments don't get dropped
• Meetings are better prepared and produce clearer follow-through
• The calendar reflects strategic priorities rather than whoever asks loudest
• Problems are surfaced early
• The Chief of Staff has more time for high-value work
• People across the organization experience you as an extension of the Chief of Staff—not as a gatekeeper who simply forwards requests

6. Establish decision rights early

This is probably the most important part of the hire.

Create three buckets:

"EA decides."

• Scheduling
• Meeting logistics
• Routine travel
• Follow-up reminders
• Standard responses
• Declining/redirecting low-value requests

"EA recommends; CoS decides."

• Calendar conflicts involving senior executives
• Priority tradeoffs
• Sensitive communications
• Exceptions to normal processes
• Which meetings deserve escalation

"CoS decides."

• Strategic priorities
• Executive-team issues
• Sensitive personnel matters
• Organizational commitments
• Anything with significant political/reputational consequences

The more decisions you can move into the first bucket over time, the more valuable the EA becomes.

7. Make the first 30 days extremely deliberate

I'd have the onboarding sequence look roughly like this:

Week 1: Shadow you obsessively. Learn your calendar, communication style, stakeholders, priorities, preferences, and recurring commitments.

Week 2: Take over calendar + logistics.

Week 3: Take over inbox triage, meeting prep, and follow-up systems.

Week 4: Start proactively managing your operating rhythm and identifying things you're doing that you shouldn't be doing.

Then establish a 30-minute weekly EA/CoS meeting:

• What is coming up?
• What am I worried about?
• What are you seeing that I'm not?
• What can you take completely off my plate?
• Where are we dropping balls?
• What systems should we improve?

A high-performing CoS role itself is often described as a "control tower" that protects executive focus and keeps priorities moving; your EA should effectively become the control tower for your control tower.

8. One mistake I'd specifically avoid

Don't accidentally hire an EA and then give them a Chief of Staff workload.

If you're expecting this person to own company strategy, independently drive major cross-functional initiatives, advise the CEO, and operate as an executive-level decision-maker, you've moved into CoS/operations territory. The two roles can be tightly coupled, but they aren't interchangeable.

Conversely, don't hire someone whose entire job is "calendar + travel" if what you really need is someone who can think with you.

My ideal setup

You — Chief of Staff → Strategy, executive advising, cross-functional priorities, operating cadence, decision-making

EA — Your operating partner → Calendar, communications, preparation, coordination, follow-through, logistics, anticipation

That pairing can be incredibly powerful because it creates a clean division: you own leverage; they eliminate friction.

If you tell me (1) the size/stage of your company, (2) who you support as CoS (CEO/founder/etc.), (3) what currently consumes most of your time, and (4) whether you want this EA in-office, hybrid, or remote, I can turn this into a specific hiring scorecard, compensation range, interview process, and 30/60/90-day plan for your situation.

• The Chief of Staff rarely has to remember logistics
• Important commitments don't get dropped
• Meetings are better prepared and produce clearer follow-through
• The calendar reflects strategic priorities rather than whoever asks loudest
• Problems are surfaced early
• The Chief of Staff has more time for high-value work
• People across the organization experience you as an extension of the Chief of Staff—not as a gatekeeper who simply forwards requests

6. Establish decision rights early

This is probably the most important part of the hire.

Create three buckets:

"EA decides."

• Scheduling
• Meeting logistics
• Routine travel
• Follow-up reminders
• Standard responses
• Declining/redirecting low-value requests

"EA recommends; CoS decides."

• Calendar conflicts involving senior executives
• Priority tradeoffs
• Sensitive communications
• Exceptions to normal processes
• Which meetings deserve escalation

"CoS decides."

• Strategic priorities
• Executive-team issues
• Sensitive personnel matters
• Organizational commitments
• Anything with significant political/reputational consequences

The more decisions you can move into the first bucket over time, the more valuable the EA becomes.

7. Make the first 30 days extremely deliberate

I'd have the onboarding sequence look roughly like this:

Week 1: Shadow you obsessively. Learn your calendar, communication style, stakeholders, priorities, preferences, and recurring commitments.

Week 2: Take over calendar + logistics.

Week 3: Take over inbox triage, meeting prep, and follow-up systems.

Week 4: Start proactively managing your operating rhythm and identifying things you're doing that you shouldn't be doing.

Then establish a 30-minute weekly EA/CoS meeting:

• What is coming up?
• What am I worried about?
• What are you seeing that I'm not?
• What can you take completely off my plate?
• Where are we dropping balls?
• What systems should we improve?

A high-performing CoS role itself is often described as a "control tower" that protects executive focus and keeps priorities moving; your EA should effectively become the control tower for your control tower.

8. One mistake I'd specifically avoid

Don't accidentally hire an EA and then give them a Chief of Staff workload.

Hiring an executive assistant (EA) to support you as a Chief of Staff (CoS) is one of the highest-leverage moves you can make. Since your role as CoS already bridges strategy and execution, your EA will essentially become your operational co-pilot, managing your bandwidth so you can protect the executive's time.

Here is a step-by-step framework to hire the right EA:

1. Define the Scope and Leverage Points
   • Audit your own calendar and tasks for two weeks. Identify what drains your time that an EA can own (e.g., complex multi-timezone scheduling, inbox triage, meeting prep documentation, travel logistics, project tracking).
   • Decide on the level of seniority you need (e.g., a junior coordinator vs. a strategic "Chief of Staff to the CoS" type EA who can handle light project management).
2. Draft a High-Context Job Description
   • Avoid a generic administrative wishlist. Highlight the unique dynamics of supporting a CoS—mention that they will act as an extension of your judgment and need high emotional intelligence (EQ).
   • Clearly outline non-negotiables: absolute discretion, proactive problem-solving, and stellar written/verbal communication.
3. Source Through Specialized Channels
   • Don't just rely on LinkedIn black holes. Post on specialized executive assistant platforms and networks.
   • Look into dedicated EA placement firms or communities like Base, Inc. or Foray Collective (or general specialized recruiting networks like Executive Assistant Network). Note: Tailor sourcing based on whether you want remote, hybrid, or local talent.
4. Design a Rigorous, Multi-Stage Interview Process
   • Screening Call (30 mins): Test for communication style, baseline professionalism, and pulse-check on career trajectory.
   • Skill/Scenario Test: Give them a realistic assignment. For example: "Here is a messy email thread and three conflicting schedules across time zones. Draft the response and propose the optimal calendar slot." or "Summarize this 10-page memo into three bullet points for an executive."
   • Behavioral/Values Interview: Probe for resourcefulness. Ask: "Tell me about a time an executive changed their mind at the absolute last minute. How did you handle the pivot?"
5. Onboard with Radical Clarity
   • Treat the first 30 days as a collaborative residency. Share your communication preferences, the executive's pet peeves, and the unwritten cultural rules of the organization.
   • Establish a daily 15-minute sync early on to build alignment, which can transition to a weekly cadence once trust is locked in.

To help tailor this strategy, could you tell me:

• What is your company size / stage (startup vs. enterprise)?
• Is this EA role remote, hybrid, or in-office?
• Are you looking for someone purely administrative or project-management heavy?

Hiring an executive assistant (EA) to support you in your role as a Chief of Staff (CoS) requires a strategic approach. As a CoS, you are likely looking for a force multiplier—someone who can manage the tactical administrative burden so you can focus on strategic execution and high-level organizational priorities.

Here is a step-by-step framework to hire the right EA for your partnership:

1. Define the Scope of the Role

• Core Responsibilities: Outline the split between calendar management, inbox triage, travel logistics, project coordination, and meeting preparation. Determine if they will also support your principal (the CEO/Executive) directly or if they will exclusively support you.
• The "Invisible" Work: Clarify expectations around confidential handling of information, gatekeeping, and anticipating your needs before you voice them.

1. Establish the Profile and Competencies

• EQ and Judgment: Look for high emotional intelligence. An EA to a CoS needs exceptional situational awareness and the ability to read a room or an email thread.
• Proactive Problem Solving: Ask yourself: do they wait for instructions, or do they present solutions alongside problems? You need a self-starter.
• Tech-Savviness: Mastery of modern productivity tools (e.g., Google Workspace, Microsoft 365, Notion, Slack, automated scheduling tools) is non-negotiable.

1. Source High-Caliber Talent

• Specialized Agencies: Utilize executive assistant placement firms like Base or Athena Executive Services that specialize in vetting high-level operational support.
• Network & Community: Tap into CoS and EA professional networks or communities like The Chief of Staff Network or Executive Assistant networks on LinkedIn and Slack.
• Job Descriptions: Write a precise job description that reflects the unique nuance of reporting to a CoS rather than a traditional executive.

1. Design a Rigorous Interview Process

• Initial Screening: Assess communication clarity, professionalism, and baseline organizational competence during a brief call.
• Competency Interview: Probe for behavioral examples. Ask: "Tell me about a time an executive changed their schedule three times in two hours—how did you handle it?" or "How do you prioritize an inbox when everything looks urgent?"
• Practical Assessment: Give them a realistic work sample test. For example, have them draft a response to a sensitive stakeholder request, triage a mock chaotic calendar, or organize a messy travel itinerary.

1. Onboard for Partnership

• Establish Operating Rhythms: Set up a daily or twice-daily sync (15 minutes) to align on priorities, landmines, and shifting contexts.
• Share the Context: An EA cannot be proactive without context. Share organizational goals, who the key players are, and your personal working style preferences.
• Gradual Delegation: Start by handing over calendar and inbox ownership, moving toward project-based autonomy as trust builds.

To help tailor this process, let me know:

• Are you hiring this EA to support you exclusively , or will they be shared with your principal?
• What is the primary bottleneck you are hoping this EA will take off your plate first?

If by “support me as Chief of Staff” you mean you want an Executive Assistant who makes you dramatically more effective in the CoS role, I’d hire for a slightly different profile than a traditional EA.

The key distinction: an EA should own your operating system—calendar, communications, logistics, follow-through, information flow—while you own the strategic/organizational work of the Chief of Staff. Current hiring guidance makes the same distinction: if the role is mostly administrative, hire an EA; a CoS should spend substantially more time on organizational priorities and execution.

1. Define the job around leverage, not tasks

I would look for an “Executive Assistant / Executive Operations Partner to the Chief of Staff” rather than a generic EA.

Their mission:

Make the Chief of Staff faster, more organized, better informed, and harder to surprise.

I'd want them to own:

• Calendar: protect your time, resolve conflicts, schedule around priorities, prepare you for important meetings.
• Inbox & communications: triage, draft routine responses, identify what actually requires your attention.
• Follow-through: maintain the action-item system and chase commitments across the organization.
• Meeting operating system: agendas, pre-reads, notes, decisions, action items and follow-ups.
• Information management: make sure you can quickly find the people, documents, metrics and context you need.
• Project coordination: keep cross-functional initiatives moving without requiring you to personally quarterback every detail.
• Travel/events: handle logistics end-to-end.
• Personal logistics, if appropriate: only to the extent that reducing personal cognitive load makes you better at the job.

A good EA should eventually be able to say, “I noticed this was going to become a problem, so I handled it,” rather than waiting for you to assign every task.

2. Hire for judgment above all else

I'd rank the attributes roughly:

1. Judgment
2. Extreme reliability
3. Proactivity
4. Organization
5. Written communication
6. Discretion/confidentiality
7. Ability to operate with ambiguity
8. Technological fluency
9. Warmth and interpersonal intelligence
10. Traditional EA experience

The biggest mistake is hiring someone who is excellent at completing instructions but needs instructions for everything.

You want someone who can distinguish:

“This needs your attention.”
from
“I can handle this.”
from
“Nobody needs to do this.”

3. Give candidates a realistic work sample

This is probably more predictive than another hour of interviewing.

Give finalists something like:

“It's Monday morning. Here are 35 emails, 12 calendar requests, 8 outstanding action items, a board meeting Thursday, an executive meeting Wednesday, and a travel change. You have 90 minutes. Show me how you would approach this.”

Then ask them to:

• prioritize the inbox;
• identify calendar conflicts;
• draft 2–3 responses;
• create a prioritized action list;
• identify what they'd escalate to you;
• explain what they would simply handle themselves.

You're testing judgment, prioritization and executive intuition, not typing speed. Those are specifically among the capabilities recommended for EA hiring.

4. Ask behavioral questions that expose how they think

I'd use questions like:

• “Tell me about a time you prevented a problem your executive didn't know was coming.”
• “Tell me about a time you disagreed with your executive's approach.”
• “How do you decide what deserves your executive's attention?”
• “What would you do if three senior people all told you their meeting was the most important?”
• “Tell me about something you took over that wasn't technically your responsibility.”
• “What information do you need from an executive to become proactive?”
• “Describe an executive relationship that didn't work. What was wrong?”
• “What's something you think executives routinely waste time on?”
• “How do you handle confidential information?”
• “If I disappear for three hours and something urgent comes up, how would you decide whether to interrupt me?”

The last question is particularly revealing.

5. Look for someone who can grow into an operator

Your ideal person may be more senior than a conventional EA but not necessarily someone with a fancy title.

Great backgrounds can include:

• EA to a CEO/founder
• EA to a COO/President
• executive operations
• project/program management
• consulting
• operations at a startup
• high-end client/service roles
• former Chief of Staff who prefers execution over strategy

I wouldn't over-index on credentials. A phenomenal EA with five years supporting a demanding executive can be much better for you than a Harvard MBA who has never actually run an executive operating system.

6. Make the reporting relationship crystal clear

They should report directly to you, with an explicit mandate to operate on your behalf.

I'd give them permission to:

• move meetings;
• decline or redirect requests;
• ask people for information;
• chase executives for deliverables;
• represent you in routine matters;
• make decisions within defined boundaries;
• tell you when you're creating unnecessary work.

That's where the leverage comes from.

7. Start with a 30/60/90-day ramp

First 30 days: learn you.

• your calendar
• communication preferences
• recurring meetings
• key people
• priorities
• decision-making patterns
• tools
• current projects
• personal quirks

Days 31–60: take ownership.

They should independently own calendar, inbox triage, meeting preparation, action tracking and logistics.

Days 61–90: anticipate.

The goal is for them to start saying:

“You have three priorities this week. I've cleared the calendar accordingly, prepared the materials for Tuesday, followed up with Finance, and flagged one decision I think you'll need to make.”

That's when you've stopped hiring an assistant and started building an executive leverage system.

8. Don't make the job description too broad

This is important. If you tell candidates:

“You'll support me with anything and everything.”

you'll attract people who are comfortable being reactive.

Instead, define the outcomes.

For example:

Success after six months:

• My calendar reflects my actual priorities.
• I rarely have to chase people for follow-up.
• Meetings end with clear owners and deadlines.
• Important information reaches me before I need it.
• Routine communication doesn't consume my attention.
• Travel/logistics require virtually no involvement from me.
• I have a single trusted person who knows what's happening across my commitments.
• I spend substantially more time on high-value CoS work.

That makes the role compelling and measurable.

One important question

Before hiring, I'd determine how much of your current pain is administrative versus strategic.

If you're spending your days thinking “I have too many meetings, too many emails, too many loose ends, and nobody is keeping track of everything,” → hire the EA.

If you're thinking “I need someone to help me drive company-wide priorities, analyze problems, influence executives and make strategic decisions,” → you're actually describing a Chief of Staff.

And if you're the Chief of Staff yourself, the sweet spot is an operator-grade EA who takes the executional infrastructure off your plate, so you can do the work only you can do. That's consistent with current guidance distinguishing the two roles.

If you tell me what you currently spend your time doing as Chief of Staff, what you wish you could stop doing, and roughly how much you'd like to spend on the hire, I can help you define the exact profile, compensation level, interview process, and first-90-day scorecard.

To hire an executive assistant (EA) to support you in your role as a Chief of Staff (CoS), you must first recognize the distinction between your macro-level strategic focus and the tactical, operational leverage an EA provides . Because a Chief of Staff amplifies executive strategy [0.36], an EA supporting a CoS acts as a force multiplier to handle inbox triage, calendar logistics, project tracking, and cross-functional coordination , freeing you up to focus on high-level organizational alignment.

Define the Scope and Split of Duties

• Calendar and Inbox Ownership: Delegate the day-to-day management of your schedule, email filtering, and meeting flow so you avoid constant context switching.
• Project and Follow-Through Tracking: Have the EA track action items emerging from leadership meetings that you oversee, ensuring cross-departmental accountability.
• Information Prep: Task them with assembling briefing documents, compiling meeting agendas, and coordinating logistics for executive or board-level sessions.

Source and Screen for High Judgment

• Look for Senior Experience: Seek a Senior Executive Assistant who possesses high emotional intelligence and sharp intuition, rather than a junior admin . They need the confidence to operate autonomously in ambiguous situations [0.40].
• Test for Anticipation: During the interview, ask scenario-based questions like, "How would you proactively unblock me if you had zero direction on a stalled project?" [0.29, 0.33]
• Evaluate Communication Polish: Since this person will often speak or write on your behalf (or interface directly with the C-suite), test their written communication and discretion [0.26].

Utilize Specialized Sourcing Channels

• Boutique Staffing Agencies: Partner with specialized executive recruitment firms (such as C-Suite Assistants or Boldly ) that pre-vet top-tier administrative partners.
• Targeted Networks: Post the role on LinkedIn or executive support networks, explicitly defining that the position supports a Chief of Staff rather than a traditional solo founder.
• Managed Support Alternatives: Consider flexible services like Wishup or Viva Talent if you need rapid onboarding for specific logistical delegation.

If you'd like, tell me:

• What percentage of your current tasks are administrative versus strategic?
• Are you looking for a remote, hybrid, or in-person assistant?

I can help you draft a custom job description tailored to your workflow.

If you’re a Chief of Staff, I’d hire an operator-grade Executive Assistant, not a traditional administrative assistant. The goal is to give you leverage: they should own the mechanics of your operating system so you can spend more time on strategy, cross-functional execution, and high-value relationships.

A useful distinction is: EA owns the “when/where/how”; you own the “why/what/who.” That division is also consistent with how experienced operators describe the EA/CoS relationship.

1. Define the job around outcomes

Don't start with "manage my calendar." Start with what you want to be different 6 months after hiring them.

I'd define 5 outcomes:

1. My calendar reflects my priorities.

   • Protect deep-work time.
   • Resolve conflicts without escalating everything.
   • Know when to say no on your behalf.
   • Build buffers around important meetings.

2. Nothing falls through the cracks.

   • Maintain a system for commitments, follow-ups, and deadlines.
   • Chase other people when necessary.
   • Surface things to you only when your intervention is actually required.

3. I walk into meetings prepared.

   • Briefing documents.
   • Attendee/context research.
   • Prior meeting notes and outstanding actions.
   • Materials and logistics.

4. My communication load is intelligently filtered.

   • Triage inbox/Slack.
   • Draft routine responses.
   • Route requests.
   • Identify what truly needs your attention.

5. The Chief of Staff function runs smoothly.

   • Coordinate leadership meetings.
   • Track decisions and action items.
   • Manage logistics for offsites, board meetings, travel, etc.
   • Keep your various workstreams synchronized.

The strongest CoS/EA hires tend to be exceptionally organized, proactive closers, strategically minded, and highly trustworthy with sensitive information.

2. Look for an "operator," not an "order taker"

I'd prioritize these characteristics:

Don't over-index on having worked at a famous company or having the exact title. A16Z's hiring guidance for Chiefs of Staff similarly recommends assessing transferable competencies rather than title history.

3. Use a practical interview process

I'd make the process 3–4 stages:

Stage 1 — 30-minute screen

Test:

• Why EA work?
• Why supporting a Chief of Staff?
• What kind of executive do you work best with?
• Tell me about a time you prevented a problem before it happened.
• How do you decide what requires escalation?

Stage 2 — Deep-dive interview

Explore actual examples of:

• Calendar disasters
• Difficult stakeholders
• Confidential information
• Last-minute travel changes
• Conflicting priorities
• An executive who changed their mind
• Following up with senior people who weren't responding

Stage 3 — Paid practical exercise

This is probably the most important step.

Give them something like:

"It's 4:30 PM on Thursday. I have six meetings tomorrow, two conflicting commitments, 150 unread emails, a board meeting Monday, and a flight Monday evening. Here's my calendar and inbox. Show me what you'd do."

Don't tell them what the "right" answer is.

You're evaluating how they think, not whether they know your particular calendar software.

Stage 4 — Final chemistry interview

Then spend substantial time together. The role is unusually intimate: this person will see how you work, what stresses you, what you're bad at, who you're talking to, and potentially highly confidential company information. Trust and working chemistry matter enormously.

Structured scorecards are useful here because they make candidates easier to compare and reduce interview bias.

4. Give the role real authority

This is where many EA hires fail.

If you tell someone:

"Manage my calendar."

but every calendar decision still requires your approval, you've hired a scheduler.

Instead:

"You are responsible for protecting my time. Make the decision whenever you reasonably can. Escalate only exceptions."

Give them permission to:

• Decline meetings.
• Move meetings.
• Ask people for information before putting something on your calendar.
• Protect focus time.
• Chase executives.
• Say "No, that doesn't work."
• Reschedule you when something more important emerges.

You can establish rules such as:

Calendar rules

• No meetings before X.
• No meetings after Y.
• X hours/week of protected focus time.
• Internal meetings require an agenda.
• Certain categories always get priority.
• Personal commitments are protected.
• Travel days have special rules.

That turns your calendar into an operating system rather than a list of appointments.

5. Build a tight relationship between you and the EA

I'd establish a short daily or near-daily cadence:

10–15 minute daily sync

• What's happening today?
• What's changed?
• What needs my attention?
• What are you handling without me?
• What am I forgetting?

And a weekly 30-minute operating review:

• What's working?
• What's creating friction?
• Where am I wasting time?
• What should you take over?
• What recurring problem should we solve permanently?

Your EA should progressively learn your preferences so that after 3–6 months you're giving fewer instructions, not more.

6. Source candidates in a few different places

I'd use a combination of:

• Your personal/professional network
• Referrals from other Chiefs of Staff and executive assistants
• Executive-assistant recruiting firms if this is a high-stakes hire
• LinkedIn
• Specialized EA recruiting communities
• Former EAs from demanding executives

Don't simply post a generic "Executive Assistant" job description. The best candidates will be attracted to a role with unusually clear scope, autonomy, and proximity to meaningful work.

7. Your job description should sound more like this

Executive Assistant to the Chief of Staff

We are looking for an exceptional Executive Assistant to partner closely with our Chief of Staff. This is an operating role for someone who thrives in a fast-moving environment, anticipates needs before they arise, and takes extraordinary ownership of details and follow-through.

You will own the Chief of Staff's calendar, travel, meeting preparation, communications workflow, and administrative operating system. You'll also support leadership meetings, strategic projects, and cross-functional coordination.

The ideal candidate has excellent judgment, strong written and verbal communication skills, exceptional organizational discipline, high emotional intelligence, and the ability to operate independently with confidential information.

We're looking for someone who doesn't wait to be told what to do. You see around corners, close loops, protect priorities, and make the people around you more effective.

The biggest hiring mistake I'd avoid

Don't hire someone because they're "nice, organized, and responsive."

Those are table stakes.

The person you really want is someone who makes you think:

"I don't know exactly how they did that, but somehow that entire problem disappeared."

That's the EA who will actually make a Chief of Staff materially more effective.
