How to Do a Reference Check That Actually Tells You Something

Most reference checks are a formality. A hiring manager calls two or three names provided by the candidate, asks a few scripted questions, gets polished answers, and checks the box. They learn almost nothing.

That's a missed opportunity. A well-run reference check is one of the highest-signal tools in the hiring process — if you know how to use it.

The problem with standard reference checks:

Candidates select their own references, which means you're talking to people who are pre-screened to say good things. The questions are generic. The answers are vague. And the whole conversation is designed to confirm a decision you've already made rather than genuinely inform it.

How to get more signal:

Go off-list. Ask the candidate for references, but also reach out to people you find independently — former colleagues you identify on LinkedIn, mutual connections, or people the candidate mentions in interviews but doesn't list formally. These conversations are more candid.

Ask about work, not character. Instead of "Would you rehire this person?", ask: "Tell me about a specific project they led. What went well? What would you have done differently?" Specific questions produce specific answers.

Ask about the conditions they thrive in. "What kind of environment brings out their best work?" and "What kind of management style do they respond well to?" These answers tell you whether your environment is one where they'll succeed.

Listen for what's not said. Hesitation, carefully qualified praise, and conspicuous omissions are often more informative than what's actually stated. If someone says "she's very detail-oriented" when you're hiring for strategic leadership, that's worth noticing.

Ask the hard question directly. "Is there anything about how this person works that I should understand before making an offer?" Said plainly and followed by silence, this question often produces the most honest answers of the whole conversation.

Reference checks done well don't change decisions very often. But they do occasionally surface the one thing that would have mattered — and that one thing is worth the extra effort every time.
