How to Build a Hiring Process That Actually Predicts Performance

Most hiring decisions hinge on a strong résumé and a confident interview, yet attrition and underperformance remain stubbornly common. The gap between who looks good in an interview and who performs on the job is one of the most expensive blind spots in business — and almost every team we work with has it.

Where the process usually breaks

Most processes test for traits that are easy to fake — confidence, polish, recall of past projects — rather than the traits the role actually demands. A candidate who interviews well is rewarded for interviewing well, not for being able to do the job.

A more reliable approach

• Define performance before the candidate

  Start with what success looks like at six months — concrete outcomes, not adjectives. Then hire toward that, not toward a personality profile.

• Use work samples, not hypotheticals

  A 30-minute task that mirrors real work tells you more than an hour of “tell me about a time when…”

• Calibrate interviewers

  The same candidate gets different scores from different interviewers. A short calibration session before each role aligns the bar.

• Score independently, then discuss

  When interviewers compare notes before submitting scores, they anchor on each other. Independent scoring surfaces real disagreement.

None of this requires new technology. It requires the discipline to test for performance directly instead of relying on signals that correlate only weakly with it.
