References are not the end of a search. They are the search.

In most recruitment processes, references are a formality conducted at the end. The decision has been made, the offer is drafted, and someone telephones two referees the candidate has nominated to confirm that nothing alarming has been overlooked.

In executive search, this approach is not merely inadequate. It is a missed opportunity to gather the most valuable evidence available about a leader.

What interviews cannot tell you

Interviews are useful. They tell you how a candidate thinks, how they present themselves and how they respond to challenge in a structured setting. But senior leaders are, almost by definition, accomplished interviewees. What an interview cannot easily reveal is how someone behaves over years: under sustained pressure, when things go wrong, and when nobody important is watching.

The people who know these things are the people who have worked with the candidate: their former bosses, peers, direct reports, board members and, sometimes, the people on the other side of the negotiating table.

“An interview shows you a leader at their best. References show you the leader everyone else has worked with.”

How we approach referencing

For every finalist in an executive search, we speak to at least ten people. Some are nominated by the candidate. Many are not, and are identified through our own research, always with care to protect the candidate's confidentiality.

These conversations are conducted personally by the lead partner, not delegated. They are structured around the specific demands of the role, and they probe for patterns rather than anecdotes. We are interested less in whether someone is good and more in the particular ways they are good, and the conditions under which they struggle.

Listening for what is not said

Experienced referees are careful. Few will say anything directly negative about a former colleague. The skill lies in hearing the hesitation, noticing what is praised faintly, and asking the follow-up question that invites a more candid answer.

Experienced referencers learn that the most revealing moment in a reference call often comes at the end, when the formal questions are done and the referee is asked, simply, whether there is anything else we should know.

Why it matters

Thorough referencing is one of the best predictors we know of an appointment that lasts. It allows a search firm to give a board an honest account of a candidate's strengths and risks, and it allows the new leader to begin their role with a realistic understanding of where they will need support.

It takes time. But in an appointment that will shape an organisation for a decade, there is no better use of a few more days.
