How to hire an executive assistant: skills to test

How to hire an executive assistant: what the role really does, the judgement and discretion to test for, AI-era skills, and an interview loop that works.

← Part of The five pillars of hiring: what assessments measure

Hiring an executive assistant is one of the highest-trust hires a leader ever makes, and one of the easiest to get wrong. This guide is for founders, chiefs of staff, and hiring managers staffing the role, because the cost of a weak hire hides for months and then surfaces all at once: a board member who felt slighted by a scheduling mix-up, a confidential term sheet forwarded to the wrong thread, an executive drowning in their own calendar while the person meant to protect it waits to be told what to do. A great executive assistant is a force multiplier who runs the leader's operating rhythm and guards their attention. A weak one is a calendar-keeper who needs managing. Both interview well, and the gap between them is almost invisible on a CV.

What does an executive assistant actually do?

An executive assistant owns a senior leader's time, attention, and information flow, making dozens of small judgement calls a day about what reaches the executive and what does not. The job is not scheduling and filing; it is deciding, on someone else's behalf, what matters. Be honest about the work before you assess it. A strong week looks like this:

• Runs the operating rhythm — protects deep-work blocks, sequences meetings so the day has a shape, and quietly resolves conflicts before the executive ever sees them.
• Triages the inbox and the door — decides what the executive answers personally, what gets a holding reply, and what never needs to surface at all.
• Handles confidential information daily — board papers, compensation, personnel matters, unannounced deals — with discretion that is assumed, never praised.
• Anticipates — books the car before the flight is confirmed, drafts the follow-up before it is asked for, notices the executive is overcommitted next Tuesday and acts.
• Communicates in the executive's voice — writes emails, briefs, and declines that sound like the leader and protect the relationship on the other end.
• Manages up and across — chases senior stakeholders for inputs, says no on the executive's behalf without causing offence, and keeps the chief of staff and the team informed.
• Owns outcomes, not tasks — success is a leader who is prepared, on time, and thinking about the right things, not an inbox at zero.

Do you actually need one?

Not every leader who feels busy needs an executive assistant. The role earns its keep when a senior person's time is genuinely the constraint on the business and the volume of scheduling, correspondence, and coordination is stealing hours that should go to decisions only they can make. Before you hire, be honest about whether the problem is really an assistant-shaped one.

You probably do not need a dedicated executive assistant yet if your calendar is chaotic mostly because your priorities are, if the coordination load could be absorbed by a shared team assistant, or if what you actually want is an operator to run projects — that is a chief of staff or an operations hire, a different spec entirely. Hiring an executive assistant to fix a discipline problem just gives you an expensive person to ignore. You do need one when the mechanics of your week reliably consume time you cannot afford to lose, when confidential coordination happens constantly, and when you are ready to delegate real judgement rather than a task list. If you are not ready to trust someone with decisions, you are not ready for this hire.

What skills separate a strong executive assistant from a plausible-sounding one?

The impostor in this role is the polished calendar-keeper: someone with a tidy CV of famous bosses and years of tenure who executes instructions flawlessly but cannot make a call without being told. They interview beautifully, because being organised and personable is exactly what an interview rewards. The force multiplier you actually want is harder to spot and rarely self-describes well. The distinction lives in a handful of skills, most of which a CV cannot show you.

• Judgement under ambiguity — when two priorities collide and the executive is unreachable, does a decision get made, and is it a defensible one?
• Discretion — do they treat confidential information as a reflex to protect, not a currency to trade, and can you tell before you have handed them anything sensitive?
• Anticipation — do they see the problem forming next week, or only the fire burning today?
• Ruthless prioritisation — can they hold the line on what matters when everything feels urgent and everyone is senior?
• Written communication in another voice — can they draft a decline that keeps a relationship warm and sounds like the executive, not like a template?
• AI fluency — can they use AI to triage an inbox and draft a reply, then catch what it got wrong and guard what should never have gone near it?

That last skill is where the role has quietly changed. AI now drafts the scheduling replies, summarises the forty-message thread, and proposes a first-pass inbox triage in seconds. That does not make the executive assistant less valuable — it moves the value up a level. The modern executive assistant curates and verifies AI output rather than forwarding it, and knows which sensitive material must never touch an unapproved tool at all. The 4D framework of AI fluency — Delegation, Description, Discernment, and Diligence — reads cleanly here: Discernment (catching the AI's plausible-but-wrong meeting time or misread priority) and Diligence (protecting confidentiality) carry the most weight, as the 4D framework of AI fluency sets out.

How do you test those skills?

Stop inferring these skills from a CV and observe them directly. The single most predictive thing you can do is a short, job-shaped work sample — the same case for work-sample tests that applies to any senior hire. Hand the candidate a realistic morning: an inbox with thirty messages of mixed urgency, a calendar with a genuine conflict between the executive's own priorities, a travel booking that has just fallen through, and one message that is clearly confidential and sitting in the wrong place. Then ask them to work it, narrating their decisions.

What you learn is judgement, not recall. Do they triage by real importance or by who shouted loudest? Do they resolve the calendar conflict with a defensible call, or freeze waiting for instruction? Do they notice the confidential message and handle it quietly, or do they mention it in passing to the wrong person? Two capabilities are especially testable here, and both have a matching assessment: attention to detail, because the mis-typed meeting time and the wrong attachment are exactly the errors that erode trust, and situational judgement, because the whole job is deciding well under ambiguity. At a capability level, an attention to detail test surfaces the precision the role demands, and a situational judgement test surfaces the calls. Run the work sample in an environment where AI tools are genuinely available rather than banned, so you see how they use them — the AI Sandbox exists for exactly this, letting you watch a candidate delegate a draft to AI and then catch it being wrong before it would have reached the executive.

What does the interview loop look like?

Keep the loop short, structured, and evidence-led. Great executive assistants are rare and heavily courted, so a slow, meandering process loses them and, worse, signals that the leader they would support is disorganised. Two or three stages is plenty when the work sample is doing the heavy lifting.

Scope the role and write the description around behaviours

Start by deciding what this executive assistant actually owns — one executive or several, how much confidential coordination, how much autonomy to say no on the leader's behalf. Write the job around the observable behaviours you will assess, not a wish-list of software; how to write a job description walks through turning outcomes into a spec that attracts the operator rather than filtering them out. This document becomes your scorecard.

Run a structured interview against a scorecard

Same questions, same order, same scoring anchors for every candidate. Unstructured chats are the biggest source of noise, and this role is almost pure judgement under ambiguity, which is exactly where structured interviews and situational prompts earn their keep. Use the interview to probe what the work sample cannot fully show: a confidentiality dilemma, a moment two senior people both demanded the executive's time, a decline that had to be delivered without burning a relationship. Score each answer independently. Because the whole role is situational judgement in hiring made concrete, weight those answers heavily, and always follow up on what the candidate personally did.

Compensation, seniority, and the first 90 days

Seniority in this role is measured by trust and scope, not years. A junior executive assistant supports a single leader on a well-defined rhythm; a senior one runs the operating cadence for multiple executives, sits close to the chief-of-staff function, and is trusted with the most sensitive material in the building. Compensation should track that trust and the market you hire in — resist anchoring purely on tenure, and hire on demonstrated judgement rather than the prestige of past employers, since paying for a famous logo is one of the reliable ways to overpay for a diary-keeper. Getting this wrong is expensive in the quiet, compounding way the cost of a bad hire always is for high-trust roles: the damage is relationships and lost executive focus, not a missed deadline.

In the first 90 days, good looks like earned autonomy. Early on, the executive assistant is still learning the leader's preferences and asking a lot; by day 90, they are making defensible calls without checking, the executive's calendar has a shape it did not have before, and confidential matters are handled so cleanly they are invisible. The clearest signal of a strong hire is subtraction — problems that used to reach the executive simply stop arriving, quietly resolved upstream. If, three months in, the leader is still explaining what to prioritise every morning, the hire is not yet working, and the honest question is whether you assessed for execution when you needed to assess for judgement.

The best executive assistants are not the ones with the most impressive bosses on their CV. They are the ones who can stand in the chaos of a leader's week, decide what truly matters, protect what must stay private, and do it all before being asked. Hire for that judgement, and test for it, or you will keep mistaking polish for the thing that multiplies a leader's time.
