How to Actually Check a Reference
Most reference checks are theater. A candidate hands over two names. Someone calls, hears pleasant things, and writes "references confirmed." Nothing was confirmed. A stranger said nice words about a person who chose them to say nice words.
In private staffing, the stakes are a family's home. Here is how we do it instead.
Verify the referee before the reference. The first question is not about the candidate. It is about the caller: did this person actually employ them, at that address, in that role, over those dates? A reference from someone who cannot place the candidate in a specific house in a specific year is not a reference. It is a favor.
Call. Do not email. A written reference is a composed document. A phone call has pauses. The pause after "would you say she was trustworthy?" tells you more than the answer.
Ask about the work, not the person. "Was he good?" invites politeness. "Walk me through what a normal Tuesday looked like" invites facts. People can improvise praise. They cannot improvise a schedule they never saw.
Ask the only question that matters. At the end: "If you were hiring again tomorrow, with your own money, would you hire this person for this role?" Anything short of an immediate yes is information. "Probably" is a no wearing manners.
Listen for the missing years. Two references covering 2019 and 2024 leave a gap. The gap is not automatically a problem. An unexplained gap is. Ask what happened in between, and then verify the answer somewhere other than the candidate.
Write it down. Who you spoke to, when, what was asked, what was said. A reference that is not documented did not happen. This is the difference between a practice and a phone call.
None of this is complicated. It is simply work, done every time, without exception. That is most of what verification means.
