Reference check
A reference check is the verification of a candidate's track record and claims by speaking to people who have worked with them, usually before an offer.
Published Updated
For senior hires, references are often taken discreetly and go beyond a candidate's named contacts, drawing on a search firm's own network to get an honest, rounded picture.
The term covers two different exercises. One is the formal reference: a conversation with people the candidate has named, with the candidate's consent, usually near the offer. The other is the backchannel or sounding, taken through a firm's own network. Both differ from a background check, which verifies documents rather than opinions, and from a written certificate of employment, which is a document the employer issues rather than a conversation with the people who saw the work.
Within a search, references come late, after the shortlist and the interviews. AESC, the executive search profession's body, describes reference checks as generally conducted once candidates reach the shortlist, with a background check usually done during the final stage of the process. They are also the first point at which what a talent map recorded about someone, from public information and the network, is tested against the accounts of people who worked with them.
In practice
Referees on a candidate's own list are chosen by the candidate, so the value of the exercise lies in how the call is run rather than in who is on the list. The questions that carry weight are specific rather than evaluative: the state the business was in, what the person actually owned as against what the title implied, how they behaved when a plan failed, and what they were like to disagree with. A common closing question is whether the referee would hire them again, and into what.
Sequencing matters because references cost the candidate exposure. An approach to a current employer can reveal a move before the candidate has resigned, so consent and timing are agreed first, and a call to a current employer may be held until an offer is signed. Backchannel references, reached through the network rather than the candidate's list, can give a rounder picture, but they sit outside the consent that governs the named list, and what may be asked, recorded, and passed on varies by jurisdiction and contract.
Confidentiality runs through the whole exercise. AESC's candidate bill of rights calls it important for candidates, sources and references alike, and warns that the unintended disclosure of an executive candidate's interest in a new position can be highly disruptive to the candidate or their current employer. A referee who learns that a colleague is in a process holds information that can travel, which is why the named list is agreed with the candidate and each call is timed. The Quantum Club's privacy pledge sets the same boundary from the member's side: interest is reviewed privately and never shared with anyone, including a current employer, without explicit consent.
Common questions
- Is a reference check the same as a background check?
- No. A reference check is a conversation about how someone worked: judgement, scope, behaviour, and whether people would work with them again. A background check is verification of fact: identity, qualifications, employment dates, and, where permitted, criminal or credit records. References are qualitative and interpretive; background screening is documentary, and what may lawfully be checked varies by jurisdiction and by role.
- When in the hiring process are references taken?
- Late, once a candidate is a serious contender and at or near the offer stage. Taking them earlier exposes a candidate who may not be hired and spends the goodwill of referees, who can only be asked so often. On senior searches the informal and formal versions can separate: soundings may run alongside the shortlist stage, while named references and any contact with a current employer wait until an offer is agreed.
- Can a former employer refuse to give a reference?
- Yes, in many places. Whether an employer owes a reference at all, and what it may contain, is a matter of jurisdiction and contract rather than a universal rule, and some employers restrict themselves by policy to confirming employment dates and job title. A refusal is therefore weak evidence about the person. It is one reason senior processes lean on people who worked alongside a candidate rather than on a human resources department. Dutch law shows what a statutory minimum can look like: at the end of the employment, and on request, the employer must issue a written certificate stating the work done and its start and end dates, and, only if the employee asks, how they met their obligations and how the employment ended.
- Should internal candidates be reference-checked too?
- For senior appointments, yes. In a 2021 Harvard Business Review article on succession, Claudio Fernández-Aráoz, Gregory Nagel and Carrie Green advise thorough assessments of all candidates, even the insiders who are well known to the board, with in-depth reference checks among them. Familiarity is not the same as evidence: the people who worked under and alongside an insider see parts of the record a board does not.
