The Reference Check Has Become a Formality
Most reference checks follow the same script. A recruiter calls the two or three names a candidate handpicked. The conversation lasts ten minutes. Everyone says the candidate was great to work with.
By the end, the hiring team has confirmed almost nothing they didn't already believe. The reference check happens because it is expected, not because it changes any decisions.
That is a problem, because references are one of the few tools that let you see a candidate through someone else's eyes before you hire them. Done well, they catch things interviews cannot.
Why Candidates Control the Narrative
The core issue is selection bias. Candidates choose who you call, so you are only ever hearing from people who agreed in advance to say something positive.
A former manager who had real concerns is simply left off the list. You will never know they existed. This is not the reference's fault or even the candidate's fault; it is how the system is built.
If you want honest signal, you have to change who you talk to and what you ask them.
Ask About Specifics, Not Generalities
"Would you hire this person again?" invites a yes almost every time, even when the honest answer is more complicated. Vague questions get vague, safe answers.
Specific questions get specific answers. Instead of asking whether someone was a good team player, ask for an example of a time they disagreed with a decision and how they handled it. Instead of asking about their strengths, ask what kind of work you would never assign them without close supervision.
The goal is to make it easier to tell a real story than to recite a compliment.
The Questions Worth Keeping
A handful of questions consistently produce useful answers:
"What would this person's biggest critic on the team have said about them?" This gives the reference permission to be honest without putting words in their mouth.
"Can you describe a specific project and what their contribution actually looked like day to day?" This tests whether the reference worked closely enough with the candidate to know anything real.
"If you were rebuilding your team today, where would this person rank compared to others you have managed?" Relative comparisons are harder to fake than absolute praise.
"What kind of manager or environment brought out their best work?" This tells you as much about fit as it does about the candidate.
Call the People Who Were Not on the List
The single highest-leverage change you can make is reaching beyond the candidate's chosen references. Ask the candidate for permission to speak with a former colleague or manager who is not on their list, ideally someone from a different team or project than the ones already covered.
Most candidates will agree, and their willingness (or hesitation) is itself informative. LinkedIn makes it easy to find former coworkers who overlapped with the candidate's tenure.
These conversations tend to be more candid because the person was not prepped in advance and has less personal stake in how the call goes.
Listen for What Is Not Said
Skilled references, especially ones coached by the candidate, know how to stay technically honest while avoiding anything damaging. The signal is often in what gets left out rather than what gets said.
A long pause before answering a simple question. Praise that stays strangely general when everything else has been specific. Enthusiasm about the person but noticeable silence about their actual output. These are worth following up on directly: "You mentioned they were easy to work with, how would you describe the quality of their work?"
Faint praise is still information. Treat it that way instead of rounding it up to a positive.
Timing Matters More Than You Think
Reference checks are usually the last step before an offer, which means they happen under time pressure and get rushed. By that point, the hiring team has already emotionally committed to the candidate, and there is a strong pull to hear what confirms the decision already made.
Try running reference checks earlier, before the final interview round, when the team is still genuinely open to what they learn. This reduces confirmation bias and gives you time to ask a strong reference follow-up questions in the next interview.
Putting It Into Practice
None of this requires a new tool or process overhaul. It requires asking better questions, talking to people the candidate did not pre-select, and paying attention to hesitation as much as enthusiasm.
Reference checks will never replace a structured interview process. But treated as a real evaluation step instead of a formality, they can surface exactly the kind of information that never comes up in a 45-minute interview, and that is worth the extra effort.
