# What to Ask on a Reference Check

> Most reference calls confirm dates and end. The value is in the two or three questions a former manager will answer honestly, and in noticing what they decline to say.

A reference call takes six minutes. Four of them establish that the candidate worked
there between the dates they said, which you could have established from a payslip, and
the remaining two produce a warm generality that would fit anybody.

Reference checking has a reputation for uselessness that it has largely earned. But the
uselessness is a property of how the call is run, not of the exercise.

## Why references have gone quiet

Two things changed and the practice did not adapt.

**Many employers now have a policy of confirming employment dates and title only.** The
reason is liability: a former manager who gives a negative reference can be sued, and
organizations of any size instruct people not to take the risk. This policy is real and
you will hit it constantly.

**And the candidate chose the referee.** Nobody nominates someone who will damage them,
so the base rate of positive references approaches one, and a positive reference carries
almost no information.

Both facts point the same way. **The value in a reference call is not the verdict. It is
the specifics, and the hesitations.**

## Get past the policy

When you reach the formal wall, two moves work more often than people expect.

Ask for the direct supervisor rather than HR. A policy of dates-only usually lives in a
human resources function; the person who actually managed the candidate is frequently
willing to talk, and is the only one who knows anything useful anyway.

Ask questions that are not about performance. "What kind of work did they do day to day"
and "what was the shift pattern" are factual, carry no liability, and tell you whether the
candidate's description of the job matches somebody else's.

**Verifying that the job was what the candidate said it was is worth the call on its own**,
and it is available even under the strictest policy.

## Listen for the pause

The most useful signal in a reference call is not a sentence. It is a hesitation before an
otherwise positive one.

Someone who liked working with a person answers immediately and warmly. Someone who is
choosing their words carefully, or who redirects to a different topic, or who confirms the
dates and offers nothing further when a natural opening exists, is telling you something
within the constraints they are working under.

**This is a signal to weigh, not a verdict to act on.** A reference who is guarded may be
following an instruction, may have had a personality clash, or may be having a difficult
day. Treat a hesitation as a reason to look harder at something specific rather than as a
reason to reject.

## Where the call belongs in the process

Late, and before the offer, not after it.

References cost the referee's goodwill as well as your time, so they belong at the point
where you have one or two candidates you genuinely intend to hire. Running them across a
whole shortlist burns relationships and produces five positive references, which is five
pieces of no information.

They also belong before the offer rather than after. A reference that raises something
material after an offer has been accepted leaves you with a problem that has no good
version. The related timing argument for credentials and clearances is in [Credential
Verification Checklist](/reports/employee-credential-verification-checklist).

## What a reference cannot do

Worth stating plainly, because reference checking is often asked to carry more weight than
it can hold.

A reference cannot tell you whether someone will do well in your role, under your
supervisor, on your schedule. It can tell you whether the job they described is the job
they had, whether the person who managed them recognizes the account, and occasionally
that something specific is worth another question. That is a narrow contribution, and it
is worth six minutes for the two candidates you are seriously considering.

Where an automated check is involved, treat its output the same way. Kariaa's own vetting
marks each requirement passed or failed on its own with the evidence and a confidence
level attached, plus an advisory fraud read, precisely so that a thin signal reads as
thin rather than as a verdict. A check that returns a bare yes is hiding the part you
needed.

<FAQ
  items={[
    {
      question: "What should I ask on a reference check?",
      answer: "Factual questions rather than performance ones, because they clear liability policies and produce checkable answers. Ask what the person did day to day, what shift they worked, who they reported to, and what the referee relied on them for. The most productive single question is what would you tell their next manager, which reframes the call as helping a colleague rather than assessing a former employee.",
    },
    {
      question: "Why do employers only confirm dates and job title?",
      answer: "Liability. A former manager who gives a negative reference can be sued, so organizations of any size instruct staff to confirm employment dates and title and nothing further. You will hit this constantly. Asking for the direct supervisor rather than the HR function, and asking factual rather than evaluative questions, gets past it more often than people expect.",
    },
    {
      question: "Are reference checks actually useful?",
      answer: "Narrowly. They cannot tell you whether someone will succeed in your role under your supervisor. They can tell you whether the job the candidate described is the job they had, which is the mismatch these calls most reliably catch, and that is available even from a dates-only employer. That is worth six minutes on the one or two people you intend to hire.",
    },
    {
      question: "When in the hiring process should reference checks happen?",
      answer: "Late, on a small number of candidates you genuinely intend to hire, and before the offer rather than after. Running references across a whole shortlist burns the referees' goodwill and produces uniformly positive answers. A reference that raises something material after an offer is accepted leaves no good options.",
    },
    {
      question: "What does it mean if a reference is hesitant?",
      answer: "Usually that they are working within an instruction rather than that something is wrong. Treat a pause or a redirect as a reason to ask a more specific question or to look harder at one area, not as a verdict. A guarded referee may be following policy, may have had a personality clash, or may simply be busy.",
