You Can't Interview Your Way to a Great Executive Hire

In the last decade, I've hired many executives. Some were great. Some were deeply wrong for the company — detrimental to the organization, expensive to replace, and exhausting to manage.

Almost every time I got it wrong, the mistake wasn't because I missed something in the interview. It was because I expected the interview to reveal something it simply can't.

I spent years convincing myself there was a perfect process. If I asked the right questions, added one more case study, looped in one more board member — I'd get certainty. I kept layering: reference calls, board interviews, culture fit exercises, panel sessions. I kept getting burned.

Here's what I finally accepted: you can never really know if someone will work out based on an interview.

Interviews are excellent at filtering out the clear No's. They expose incompetence, arrogance, obvious misalignment. But once you've removed the clear mismatches, you're left with a pool of maybes. And turning a maybe into a definitive yes is usually just a guess dressed up as data.

The only real signal comes from watching someone operate in real conditions.

What a decade of bad hires taught me

When I look back at the executive hires that worked, they shared two traits: they proved themselves through meaningful work before signing the offer letter, or they were internal promotions who already knew the business and the culture.

The ones that didn't work? Almost universally, they looked great in interviews. Reference calls were glowing. The board liked them. We were all fooled by a good presentation.

Executives can be as polished in an interview as a startup demo is in a pitch meeting. It doesn't mean they'll survive production.

Here are the eight principles I now follow.

1. Try before you buy

I've stopped judging executives by presentations. Instead, I bring candidates in as advisors for up to six months and work on a real problem together. This reveals how they handle pushback, deliver under pressure, and mesh with the culture.

By the time we extend an offer, onboarding is nearly done. We already know exactly who they are — not who they perform as in a conference room.

2. Hire for the next 18 months, not the exit

One of the most common hiring mistakes founders make is choosing a Stage 5 executive for a Stage 2 company, hoping they'll grow into what's needed later. It rarely works. No executive stays forever, and optimizing for a future state usually means hiring someone who's wrong for what you need right now.

If you need a builder today, don't hire a scaler who hasn't touched a CRM in five years just because you might need one in three years. Hire for the next 18 to 24 months. Solve the problem in front of you.

3. Run the energy audit

After every conversation with a candidate, ask yourself one question: do I feel more energized or more drained?

If you dread the next meeting, or feel heavier after each interaction, that's your answer. Executive relationships require constant, high-bandwidth communication — strategic decisions, hard feedback, navigating conflict. If the dynamic drains you during the courtship, alignment will collapse under pressure.

Trust what your body is telling you before your brain talks you out of it.

4. Watch for gatekeeping

I want to be able to talk to anyone in the company — collect unfiltered context, engage with teams at every level, hear what's actually happening. So when a leader asks me not to speak with their direct reports because it might "stress the team," that's a major warning sign.

Every time I've seen this, the real issue wasn't stress. It was control. They were managing information flow to manage the narrative.

If a leader blocks access to their team, it's an instant dealbreaker. Great leaders welcome transparency because they have nothing to hide.

5. Prioritize home-grown talent — but not exclusively

Promoting from within is high-leverage. You already know how someone works, how they think, and how they handle pressure. There are no surprises on culture fit because they've been living it.

But an entire leadership team built from internal promotions risks becoming an echo chamber. The right balance: elevate strong internal talent, then complement them with external hires — ideally ones who've already proven themselves through the advisor model before receiving an offer.

6. Ignore the reference calls

I no longer put meaningful weight on reference calls. Candidates only connect you with fans, and fans offer curated praise that rarely tells you anything you didn't already suspect.

What reference calls can do: confirm specific concerns. If something already feels off, use a reference call to probe it directly. Don't use it as a source of signal — use it as a tool for validation or disconfirmation.

If something feels wrong, a glowing reference shouldn't talk you out of what you already know.

7. Hire people you actually like

This isn't something that shows up in HR frameworks, but it matters enormously in a startup: hire people you genuinely like. You'll spend more waking hours with your leadership team than with your own family.

When you like someone, trust builds faster, collaboration comes easier, and hard conversations don't damage the relationship. When you don't — when you just respect their credentials — every difficult moment becomes a negotiation.

Liking someone isn't a soft criterion. At the executive level, it's a performance variable.

8. Build a clear exit ramp

Because you can't truly know if an executive will work until they start, build a structured exit ramp into every hire. Make the three-month mark an explicit decision point for both sides — not a formality, not a rubber stamp.

In reality, you'll feel the fit within the first month. If something is off early, it won't correct itself through willpower or patience. Accepting that uncertainty is part of the process removes ego from fixing bad hires and makes it easier to part ways before real damage is done.

The goal isn't to engineer a perfect interview. It's to create conditions where real work and real alignment can emerge before a title is ever formalized.

The best executive hires I've made didn't feel like hiring decisions by the time we shook hands. They felt like a formality — because the real decision had already been made, in the work we'd done together.
