What References Should You Actually Check Before Hiring an Executive?

PRL International | prlinternational.com

The references you should actually check before hiring an executive are the ones the candidate did not give you, because the references a candidate hands over are pre-screened to say good things, and the real picture comes from the people they conveniently left off the list. Most companies treat reference checking as a final formality, a box to tick after the decision is already made. The companies that avoid expensive executive mis-hires treat it as the last real chance to find out whether the person they are about to bet the business on is who they appeared to be across five interviews.

PRL International is a retained executive search firm serving Pittsburgh and Western Pennsylvania, specializing in senior-level placements in energy, manufacturing, and mid-market companies, and in more than 30 years of checking references on senior leaders we have found that the most important conversation in the entire search is almost always the one the candidate did not arrange. Here is how to do reference checking on an executive the way it actually protects you.

Why Are the References a Candidate Gives You Almost Useless?

The references a candidate provides are almost useless on their own because no rational executive hands you a reference who will say anything damaging. By the time a candidate gives you three names, those people have been called in advance, briefed on the role, and asked to speak well of the candidate. What you get from them is a rehearsed, uniformly positive picture that tells you very little, because it was engineered to tell you exactly what the candidate wanted you to hear.

This does not mean candidate-supplied references are worthless, but it means they are a starting point, not an answer. The value in calling them is not the praise, it is the texture around the praise, the small hesitations, the things they decline to say, and the names they mention in passing. A skilled reference call turns a candidate's own reference into a source of new leads, because the question that matters is not whether this person liked the candidate, it is who else worked closely with them. In more than 30 years of retained search, the most useful reference we have ever taken almost always started as a name dropped casually by one of the candidate's own chosen references.

How Do You Find the References a Candidate Did Not Give You?

You find the references a candidate did not provide by mapping the people who worked above, below, and alongside them at each role, and reaching those people directly rather than waiting to be introduced. A candidate controls the references they offer. They do not control the former direct report who watched how they actually treated their team, the peer who competed with them for resources, or the board member who saw how they performed under real pressure. Those are the people who give you the unvarnished picture, and reaching them is a matter of network and effort, not luck.

"Be courteous to all, but intimate with few, and let those few be well tried before you give them your confidence." (George Washington)

That is the entire discipline of executive reference checking in one sentence. You are deciding whether to give this person your confidence, and the responsible thing is to make sure they are well tried first, by people who have no incentive to manage the message. This is one of the clearest advantages of a retained search firm with a real network: the firm can reach the off-list references discreetly and credibly, because it already has relationships across the industry. A company running its own search rarely can, which is why most internal reference checks default to calling the three names on the sheet.

What Questions Should You Actually Ask in an Executive Reference Check?

The questions that actually matter in an executive reference check are behavioral and specific, designed to surface how the candidate performed under real conditions rather than to confirm what you already believe. The single most revealing question is some version of: knowing what you know, would you hire this person again for a role like this, and why. The answer, and just as importantly the speed and tone of the answer, tells you more than a dozen questions about strengths.

Beyond that, the questions worth asking are concrete. How did this person handle a decision that turned out to be wrong. What did they do when they disagreed with the board or the CEO. How did the strongest person on their team describe working for them. What would the candidate's biggest critic at the company say, and would that criticism be fair. Vague questions get vague answers. Specific questions about real situations get real answers, because they are hard to deflect with a rehearsed line. We wrote about the related warning signs in he looks perfect on paper, and here is why that should worry you, and the same principle applies to references: a perfectly clean, entirely positive reference with no texture or nuance is itself a warning sign, because no real executive career is that smooth.

What Are the Biggest Mistakes Companies Make Checking Executive References?

The biggest mistake companies make in executive reference checking is doing it after the decision is already made, which turns the entire exercise into a search for confirmation rather than truth. By the time most companies pick up the phone, they have emotionally committed to the candidate, and so they hear the positives loudly and explain away the hesitations. A reference check done to confirm a decision is worthless. A reference check done while the decision is genuinely still open is one of the most valuable hours in the whole process.

The second major mistake is delegating reference checks to someone junior who reads from a script and records the answers without hearing them. A reference call is a skilled conversation, not a survey. The person making the call needs the experience to notice when a reference goes carefully quiet, to ask the follow-up that the script does not contain, and to interpret what a pause actually means. In more than 30 years of placing senior leaders, we have found that the difference between a reference check that protects the company and one that merely documents the hire is entirely in who makes the call and whether they know what they are listening for.

How Does Reference Checking Fit Into the Whole Search?

Reference checking fits into a well-run search as the confirmation of conclusions you have already begun forming, not as a separate event bolted on at the end. By the time a strong search reaches references, the recruiter has spent weeks in candid conversation with the candidate and has already developed a clear, evidence-based view of who they are. The references then either confirm that view or, occasionally, surface something that changes it, and both outcomes are valuable. A search that treats references as an afterthought has wasted the most important verification tool it has.

This is also why reference checking cannot be separated from the rest of the process. The first interview, the assessment, and the references are all part of one continuous effort to find out whether this leader can actually do the job, and we wrote about the front end of that in why the first interview is not a warmup. In more than 30 years of retained search, the searches that produced leaders who were still thriving years later were almost always the ones where the reference work was treated as seriously as the interviews. PRL International runs reference checks as a core part of every search, reaching beyond the candidate's chosen list to the people who actually know the truth.

The reference check is the last moment before you give a near-stranger real power over your company. Done as a formality, it protects no one. Done properly, by someone who knows what to ask and who to ask, it is the cheapest insurance you will ever buy.

What Do You Do When a Former Employer Will Only Confirm Dates of Employment?

When a former employer will only confirm dates of employment, you go around the company and reach the individuals directly, because the corporate policy that limits references to dates and title does not bind the individual people who worked with the candidate. Many large companies instruct HR to release nothing but employment dates to limit legal exposure, and a company relying on official channels for an executive reference will hit that wall every time. It is one more reason official, candidate-supplied references are so thin.

The way through is to reach the actual humans, the former boss who has since retired or moved to another company, the peer who now runs a different business, the direct report who has moved on and has no reason to protect the candidate or the old employer. Once those people are speaking as individuals rather than on behalf of a company, the corporate policy is irrelevant, and they will speak candidly. This is, again, where a search firm with a deep network has a structural advantage over a company running its own check. The firm can often find someone it already knows who worked with the candidate, and a reference conversation between two people who trust each other is worth ten careful calls to strangers reading from a policy.

It is worth saying plainly that this has to be done ethically and professionally. The goal is honest, fair information about how someone performed, gathered through legitimate professional relationships, not gossip or anything that crosses a line. Done right, back-channel reference work is simply diligence: talking to the people who actually know, in a way that respects both the candidate and the people providing the information.

How Many References Are Enough for an Executive Hire?

For a senior executive hire, enough references means enough to see a consistent pattern from multiple vantage points, which in practice is usually somewhere between six and ten conversations rather than the standard three. Three references, especially three the candidate selected, give you a single angle on the person. Six to ten, drawn from people who saw the candidate from above, below, and beside, give you a pattern, and the pattern is what you are actually after. One glowing reference proves nothing. One critical reference proves nothing either. The consistency across many is what tells the truth.

The other reason the number matters is that contradiction is information. When a former boss describes a decisive, collaborative leader and three former direct reports describe someone who steamrolled the team, that contradiction is the most useful thing you will learn in the entire search, and you only find it by talking to enough people to see both sides. In more than 30 years of placing senior leaders across energy, manufacturing, and mid-market companies in Pittsburgh and Western Pennsylvania, the mis-hires we have seen companies make almost always traced back to a reference process that stopped at three friendly voices and never reached the people who would have told them the truth. The cost of those few extra conversations is trivial against the cost of a failed executive hire, and that math never changes.
