Most employers still check references the same way they did in 1998. Ask the candidate for three names, call the three names, hear three glowing reviews, and call it diligence. It isn’t. It’s a formality with a phone number attached.
The problem is simple. Listed references are chosen by the candidate. They’ve been warned the call is coming, they’ve often been coached on what to emphasize, and the worst-case scenario is that one of them says something lukewarm. You’re hearing from the people who like the candidate most, about the version of the candidate who showed up on their best days. That tells you almost nothing you didn’t already learn in the interview.
We stopped relying on listed references years ago. What we do instead is backchannel, and it’s the single most reliable predictor of on-the-job performance we have.
What backchannel actually means
A backchannel call is a conversation with someone who knows the candidate’s work but was not put forward by the candidate. A former peer. A client who dealt with them directly. A manager from two jobs ago who the candidate didn’t list because the relationship ended awkwardly, or simply because they didn’t think of them. Nobody prepped these people. Nobody told them what to say. That’s exactly why their answers are worth something.
Specifically, we’re looking for people who saw the candidate under pressure, not just in a good quarter. The unscripted version of someone’s reputation is usually more accurate than the polished one.
Think about what a listed reference can’t tell you: how the candidate treated people who couldn’t help their career, how they handled a missed target, whether the team stayed or scattered after they left. Those are the facts that predict your next twelve months, and they live with people who weren’t on the list.
How to find the right people
You don’t need a special database. You need a few honest minutes and a willingness to ask for introductions.
- LinkedIn second-degree connections. Look at who you share with the candidate, then look at who worked at the same company during the same window. Two overlapping tenures is usually enough to justify a polite message.
- Industry contacts. In a market like ours, someone you already know almost always knows someone who worked with the candidate. One text asking “do you know anyone at that firm?” saves a week.
- Prior portfolio companies and clients. For senior hires especially, the people who bought from the candidate, or sat across the table from them in negotiations, will tell you things a manager never would.
The four questions that get real signal
Ten minutes is enough if you ask the right things. We use the same four almost every time.
- “What was it like to work with them when things went sideways?” Everyone is easy to work with when the numbers are good. The answer to this question separates people who own problems from people who manage perceptions.
- “Where did they need the most support?” This is a softer way to ask about weaknesses. Almost nobody will say “they have no weaknesses,” and the pause before the answer is often more informative than the answer itself.
- “Would you hire them again, and in what role?” The second half matters. A yes with a caveat about the role is a precise piece of information about fit.
- “Is there anything I should be asking you that I haven’t?” Roughly one call in four, this is where the real answer shows up.
A few rules we hold ourselves to
Backchannel has to be done carefully, or it becomes a liability. Never call a current employer without the candidate’s permission, and never at a stage where it could cost them their job. We tell candidates up front that we backchannel, we get their consent for any current-employer contact, and we treat everything we hear as confidential. The goal is a better decision, not gossip.
It’s also worth saying that a single negative comment isn’t a verdict. We look for patterns across two or three calls. One person with a grudge is noise. Three people independently describing the same behavior is a finding.
If you take one thing from this, take this: stop treating the reference list as the end of your diligence. Call the people on it if you like, then make two calls the candidate didn’t see coming. You’ll learn more in twenty minutes than the standard process gives you in a week.
