How executives evaluate executive assistant candidates (and how to avoid a bad hire)

TL;DR

How to hire an executive assistant? Most EAs who fail due so not because they lack skills, but because they struggle with judgment calls and tolerating ambiguity. This guide helps experienced executives understand how to hire a great EA by evaluating EA traits that matter most: judgment, prioritization, and clarity under pressure. It covers real-world evaluation signals, common misjudgments, early red flags, and the qualities that separate technically competent from truly effective executive assistants.

“My EA is taking the load off me in places where I’d need it; hiring someone good can take a while, so I’d be unhappy to no longer be able to work with my EA, or with Viva, who I presume would be able to fill a role quickly.” – Troy Astorino, Co-founder and CTO, Picnic Health

Gallup reports that replacing an employee can cost one-half to two times their annual salary, and most executives don’t realize they’ve hired the wrong executive assistant until it’s too late. On paper, the candidate checked every box: years of experience, glowing references, polished interviews. But a few weeks in, something’s off. Priorities are missed. Communication gets murky. Tasks are executed, but not with the judgment or anticipation you need.

This guide is for experienced executives at enterprise-scale companies who are doubting how to hire a great EA and want to get it right. We’re going beyond resumes and interviews to look at what really signals success if you want to hire an ea: early judgment calls, prioritization under pressure, communication clarity, and real-world performance. If you’re wondering how to hire a great EA, this post will show you how to evaluate what truly matters and avoid the costly mistakes even seasoned leaders make.

Why most hiring decisions go wrong

The problem with how to hire an executive assistant isn’t a lack of experience. It’s a misread of what “qualified” looks like.

Too many executives over-index on polish: a work history with impressive companies, fluency in tools like Superhuman or Notion, confident responses in interviews. But being “good on paper” doesn’t mean someone can handle the unstructured, high-pressure, fast-context-switching environment of your actual day-to-day operations.

Consider this quote from Stephanie Landa, CAO at EarthOptics: “Cynthia isn’t just executing the tasks we request, which is what most assistants do. She consistently introduces new methodologies or ideas that are different and even better than what we were thinking.”

A candidate who is a fast executor but lacks instincts will miss that moment entirely. That’s the gap you need to fill if you want to hire an ea that helps you move the needle.

What you should evaluate if you want to hire an EA

If you’re serious about how to hire a great EA, you need to evaluate for judgment, not just experience. Here are the signals that matter:

1. Judgment in unstructured scenarios

Great EAs don’t just wait for instructions. They look at a range of inputs: Slack threads, shifting meetings, and decide what matters.

How to hire a great EA? In trial tasks or live work simulations, look for:

• Can they identify missing context and ask the right clarifying questions?
• Do they flag ambiguous decisions instead of guessing?
• How do they handle a vague brief with conflicting inputs?

One exec told us: “My EA went through some of my old Slack conversations from before she even started supporting me and proactively found things she could take off my plate. She really goes out of her way to help.“

2. Prioritization under pressure

A good EA can sort urgent from important. A great EA shields you from noise. During onboarding, listen to how they explain tradeoffs:

• Do they defer all prioritization to you or offer proposals?
• Can they explain their logic in plain terms?
• How do they triage when your inbox, calendar, and Slack all explode at once?

Effective, high-performing EAs use tools like Gmail filters, Slack channel tagging, or scheduling systems to make judgment calls in real time. If you’re ready to hire an ea, make sure you test for the right skills.

3. Communication clarity

Effective EAs write, speak, and summarize clearly under pressure. That doesn’t mean perfect grammar. It means useful, contextual, and timely communication. 

“My EA has been digesting and synthesizing what I need to know from my email, summarizing it in a form that helps me clear up my inbox in 20 minutes. That’s not a way I’ve ever been supported in the past.” – Anthony Gregorio, VP of Strategy and Development, Veho 

If you’re ready to hire an ea, remember to test this by asking them to summarize a meeting, triage an email thread, or prepare a draft update to your board or team.

How to hire a great EA? Watch for:

• Do they grasp what tone is appropriate?
• Can they turn dense updates into clean executive summaries?
• Are they confident in clarifying instead of guessing?

How to avoid common mistakes when hiring an EA

Even seasoned execs fall into these traps:

Misjudgment #1: Hiring for chemistry over calibration

Liking someone isn’t enough. You need alignment on standards and speed.

Fix: Define what “good” looks like before you meet candidates. Calibrate on what matters most: response time, judgment, proactivity, and stick to it.

Misjudgment #2: Mistaking responsiveness for ownership

A fast reply is not the same as real ownership. Many execs confuse eagerness with capability. This is especially important since, according to Forbes, delegation was identified as the top skill for preventing burnout, yet only 19% of manager candidates demonstrate strong delegation skills.

Fix: During interviews, probe for how they’ve made decisions without being asked. Ask: Tell me about a time you took initiative in an ambiguous situation. What did you do, and what happened next?

Misjudgment #3: Assuming skill = fit

Someone may be technically strong but unable to thrive in your specific chaos.

Fix: Introduce real scenarios early. Don’t wait until after hiring to discover they freeze in high-stakes situations.

One of our customers, Ryan Green, CEO at Gridwise, told us: “My EA has really integrated herself into the team. She is super proactive. Not only does she address the tasks I present, but she consistently suggests areas to help me be more productive.”

What are some red flags when hiring an EA?

Most hiring regrets become obvious fast, if you’re paying attention. Here’s what to watch for:

• They wait for you to notice errors, instead of flagging them first.
• They execute tasks correctly but never ask, “What’s the goal here?”
• You start shielding them from complexity instead of trusting them with more.

If your EA doesn’t start increasing your surface area within 3 weeks: solving problems, reducing back-and-forth, or freeing up mental space, they’re not the right fit.

“The most challenging role we had to hire for at Shippo was an EA, we just couldn’t get it right. We were finding good people but struggled to find candidates who could keep up with the speed and level we expected. Until we decided to onboard a Viva EA.” – Teryle Aguilar, SVP of People at Shippo 

Real-world complexity: The test most EAs fail

Let’s say you need to rebook a trip while overseas, reschedule a major meeting, and send updates to 5 stakeholders, all before your next call. What happens?

This is where theory meets practice. A technically skilled EA may freeze or do only what you explicitly ask. An effective EA will:

• Put you on the next available flight and arrange new check-in times with the hotel
• Find the next available time for all meeting attendees and send new invites over
• Draft an email to keep all stakeholders up to date

These aren’t rare tasks. This is the job.

Why judgment can’t be trained after the hire

You can teach someone how to use Superhuman. You can’t teach anticipation.

We’ve seen technically competent EAs fail because they never developed the ability to see around corners. They wait. They ask questions, but the wrong ones. They avoid ambiguity instead of stepping into it.

That’s why we help our customers evaluate judgment from day one.

How Viva screens for the right EAs

At Viva, we’re focused on exactly this: hiring and training EAs who demonstrate sharp judgment, clear thinking, and executive-ready communication from day one.

Our customers range from Series A to public tech companies, and we often pair 2–3 executives per EA based on judgment and capacity. They support inbox triage, meeting prep, investor comms, hiring coordination, and much more.

As Latoya Freeman, Exec Ops Partner at Notion puts it, “The business impact that Viva has had on the team is all the time they’ve given back to their executives. They would not been able to do half the things they’ve done if they didn’t have these EAs help them.”

Final checklist: How to hire an executive assistant who thrives in your world

Before you extend an offer, ask:

• Can they make decisions with limited information?
• Have they demonstrated judgment in messy, ambiguous situations?
• Did they take ownership without being micromanaged?
• Will they reduce your cognitive load or add to it?

If the answer isn’t a confident yes, keep looking. You’re not hiring support. You’re hiring leverage.
