The standard reference call is a ritual both sides perform: the referee says the candidate was reliable and pleasant, the employer ticks a box, and nobody learns anything. Then occasionally a hire goes badly wrong, someone finally calls the old employer, and hears: well, you never asked. The gap between those two calls is technique - and knowing what references can and cannot do for you.
- References verify facts and calibrate onboarding; they rarely predict performance on their own. Use them late, on finalists only.
- Referees almost never volunteer negatives - the signal is in specifics, hesitations and what praise is conspicuously missing.
- Ask about behaviour in defined situations, not opinions of character; make declining to answer an informative act.
- The best single question remains: would you hire this person again - and the pause before the answer.
What references are actually for
Three jobs, none of which is "predicting performance". Verification: that the claimed role, dates and responsibilities are real - CV inflation is common enough that this alone justifies the call where history drives pay or trust. Risk screening: for roles with cash, keys, vulnerable people or safety exposure, the reference is a due-diligence layer that also protects you legally - in care and childcare it is mandatory practice, as covered in hiring childcare staff. Calibration: learning how this person is best managed - what made them thrive, what wore them down - which turns a reference from gatekeeping into an onboarding brief. Performance itself is better predicted upstream by scored, situational screening and observed work: the instruments in screening questions and trial shifts.
Questions that defeat politeness
- Anchor in situations, not character. "How did she handle the Saturday rush when someone called in sick?" produces memory; "was she reliable?" produces etiquette.
- Ask for ranking, not rating. "Compared with others who have done this job for you, where did he sit?" - referees who would never criticise will still place someone honestly in a field.
- Ask the management question. "What would his next manager need to know to get the best from him?" gives referees a legitimate channel for the caveat they would not volunteer as criticism.
- Close with the classic. "Would you hire her again if she applied tomorrow?" - then stay silent. The immediate yes, the pause, and the "in the right role..." are three different answers.
Reading the negative space
Referees communicate by omission. Praise for punctuality and friendliness on a question about work quality is an answer. "I would rather just confirm the dates" from a referee the candidate personally chose is an answer. Warmth about the person paired with silence about rehiring is an answer. None of these is a verdict on its own - policies, personalities and history you do not know all produce false signals - so treat a concerning reference as a prompt for one more call and a direct, fair conversation with the candidate, not as a quiet rejection. And keep notes factual: in much of Europe candidates can lawfully access what was recorded about them, and your notes should survive that reading.
Process that keeps it fair and fast
Reference finalists only - one or two people, two referees each, fifteen minutes a call. Get the candidate's consent and correct phone numbers, but insist on speaking to named managers in a work context rather than a friend with a job title; a two-minute LinkedIn check on each referee is cheap insurance. Apply the same questions to every finalist for the role - consistency is both fairness and better signal. And when the reference lands as a conditional offer's final gate, tell the candidate what came back if it changes the outcome; how you handle that conversation is employer brand too, in the spirit of the rejection guide.
The takeaway
References are a scalpel, not a net: used late, on finalists, with situation-anchored questions and an ear for what is not said, they verify the past and de-risk the trusted roles. Let structured screening and observed work predict performance; let the reference call do the two jobs it is actually good at - truth and calibration.
Screen before you reference.
Qwiza's scored quizzes verify ability and availability at the top of the funnel, so reference calls are a final check on two finalists, not a fishing trip on twenty - 48-hour pilot target.

Are reference checks even worth doing for frontline roles?
Selectively, yes. For volume seasonal intake, structured screening plus a trial shift predicts better than any phone call, and referencing every applicant is theatre. Reference the finalists for roles with keys, cash, vulnerable people or team leadership - and always verify employment facts where a claimed history drives pay. The care and childcare sectors are the exception where references are mandatory practice on everyone, full stop.
What can a previous employer legally say about a candidate?
Practices differ by country, but two patterns are near-universal: employers may confirm factual employment details, and anything more must be honest and fair - defamatory inventions and spiteful embellishments create liability, which is why many companies restrict referees to dates-and-role confirmations. In several European countries employees are entitled to a formal written reference with regulated wording. Treat a facts-only response as company policy, not as a hidden warning - and ask the candidate for an additional referee who is free to speak.
What if the candidate does not want me calling their current employer?
Respect it - it is the norm, not a red flag; calling a current boss can cost the candidate their job before yours is signed. Take referees from previous roles, and where the current role is the only meaningful history, make any offer conditional on a satisfactory reference taken after acceptance. What does deserve scrutiny: a long career that cannot produce any referee at all, or names that keep being unreachable in ways that feel arranged.
