Reference check prep: what your references should know
Your references can sink an offer without realizing it. Not because they dislike you — because nobody told them what the role needs. Here's how to brief them in five minutes.
A friend of mine lost an offer last year at the reference stage. Not because her references said anything bad. Because one of them, a former VP, rambled for ten minutes about her "strong writing skills" when the hiring manager had called to verify she could run a fifteen-person team.
The VP wasn't wrong. He just wasn't useful. And the hiring manager hung up with a vague feeling of "I didn't hear what I needed to hear."
That call sank the offer.
Most people treat reference checks as a formality. The candidate hands over three names, the recruiter calls them, a box gets ticked. If your reference likes you, you pass.
That's not how it works. Reference checks are the last place offers die, and they die quietly.
Why references fail even when they love you
A reference call has maybe three useful questions in it. The hiring manager isn't trying to discover if you're a good person. They've already decided you probably are. They're trying to stress-test one or two specific worries.
Maybe the worry is: "she's coming from a bigger company, can she operate without a lot of infrastructure?" Maybe it's: "his last role was individual contributor, can he actually manage?" Maybe it's: "she interviewed well but I couldn't tell if she'd push back on me when I'm wrong."
Your reference has no idea what the specific worry is. So they tell the story they remember best, which is usually from three years ago on a project that's irrelevant to the current role. They mean well. They just fire their praise at the wrong target.
The five-minute brief
Before you hand over anyone's name, you owe them a short briefing call or email. Here's what it should contain.
The role. Not a link to the job description. One sentence: "I'm interviewing for Head of Ops at a 40-person Series B logistics company, reporting to the COO."
Who's calling. Name, title, company. Let the reference Google them before the call.
The two things the hiring manager is worried about. You usually know this from interviews. Did they keep asking about team size? That's the worry. Did they ask three times about stakeholder management? That's the worry.
The stories you'd like them to have ready. Not scripted lines. Actual situations from your time working together that speak to those worries.
Here's an actual email I'd send.
Subject: Reference call heads-up — WunderCo Head of Ops
Hey Mark —
Thanks again for agreeing to be a reference. A woman named Priya Natarajan (COO at WunderCo) is going to call you this week. She'll be short — probably fifteen minutes.
The role is Head of Ops at a 40-person logistics startup in Berlin. I'd be running a team of twelve across ops, support, and vendor management.
Two things I think she's trying to get comfortable with:
- Whether I can actually manage people (most of my time with you I was IC)
- Whether I push back when I disagree with a decision
If useful, the mentoring thing I did with the junior analysts in 2023 is a good story for #1. And that argument we had about the Q2 roadmap — where I turned out to be right about the shipping carrier switch — is honestly a great story for #2 if you're willing to tell it.
No pressure to use these, just in case it helps you prep. Call me if you want to talk through anything.

Five minutes of your time. The reference now walks into that call knowing exactly what to do.
What to withhold
Don't coach them on what to say. That's different from briefing. If the reference sounds rehearsed, the hiring manager hears it instantly, and now you have a bigger problem than a vague reference.
Don't list your accomplishments. They already know. You're not reminding them you're great, you're reminding them which version of "great" is relevant right now.
Don't send more than three bullets. If the email is longer than the one above, you're overcoaching.
Pick references based on role fit, not loyalty
People default to references who like them most. Wrong metric. Pick references who can speak to the specific worry.
If the role is about managing senior stakeholders, your old peer isn't the right reference. Your old skip-level is. If the role is about scrappy execution, the VP at BigCo you worked with for six months isn't the right reference. The founder you did contract work for is.
Match the reference to the job. Swap them out per role if you have to.
Takeaway
Your references aren't endorsers. They're witnesses. A good witness knows what question they're being called to answer. Tell them.
