Hiring Is a Bet
How much can four hours actually tell you?
The idea
A hiring decision is a probabilistic judgement made from a small, unrepresentative sample of someone's behaviour.
In the real world
Four hours of interviews to predict years of work.
Going deeper
A few hours of interviews is a small and unrepresentative sample of how someone works over years, so hiring produces wrong estimates at some rate no matter how good the process is.
That reframing changes what to improve. Rather than seeking certainty, the levers are making the sample more like the job — a work sample, a paid trial, a realistic problem rather than a puzzle — and shortening the time to notice a mismatch. A process that never makes a bad hire is usually one that rejects too many good candidates, which is a cost that never shows up because those people are invisible.
Where it stops applying
Treating people as bets can slide into treating them as disposable. The framing is about the quality of information available at decision time, not about commitment afterwards.
Why it matters
It shifts the goal from being certain, which is impossible, to improving the odds and limiting the damage of being wrong.

Test yourself
A candidate interviews superbly and struggles in the role. The process is called a failure. What is the fairer reading?
Show the answer
That a low-information sample produced a wrong estimate, which will happen at some rate no matter how good the process. The useful questions are whether the sample could be made more like the job, and how quickly a mismatch is noticed and handled.
