Reference Check

How it works

A reference check is contacting people a candidate has previously worked for or with — usually former managers or colleagues — to verify their work history and get an outside perspective on their performance, typically done late in the hiring process.

A reference check typically follows a short, consistent set of questions across every candidate — confirming employment dates and role, then asking about performance, reliability, and reasons for leaving — asked of two or three references a candidate provides. Because references are chosen by the candidate, the responses tend to be positive by default; the real signal usually comes from specifics and tone (a reference who answers questions with concrete examples versus one who's noticeably vague or hesitant) rather than the presence or absence of praise itself.

In staffing & high-volume hiring

Reference checks usually happen after a candidate has cleared interviews but before (or alongside) an offer, since they're meant to confirm what the interview process suggested rather than replace it. At high volume, they're often the step most likely to get skipped under time pressure — which is a real tradeoff, since a rushed or skipped reference check trades a small amount of speed for less certainty about a hire that's about to be locked in.

Common mistakes

• Only checking whether a reference says anything explicitly negative, rather than reading the specificity and enthusiasm of their answers, which is often where the real signal is.
• Skipping reference checks entirely under time pressure for roles where the tradeoff between speed and certainty genuinely matters.
• Asking vague, open-ended questions instead of a consistent set that lets responses be compared across candidates the same way a structured interview does.
