Calibrating panels so five interviewers score like one

Panel disagreement isn't a sign of thoroughness. It's usually a sign of an uncalibrated rubric.

The playbook.

Run a calibration session before the pipeline opens

Have every panelist independently score the same two or three sample transcripts against the rubric, then compare. Large gaps reveal exactly where the rubric is ambiguous, before it costs you a real candidate.

Define what each score point actually means

A '4 out of 5' means something different to every interviewer unless you write down what separates a 3 from a 4 from a 5, with a concrete example for each. Vague scales are where calibration breaks down first.

Debrief disagreements, don't average them

When two panelists land far apart on the same candidate, the fix isn't splitting the difference — it's a short conversation about what each of them actually observed. The gap itself is useful signal.

Rotate a lightweight audit

Periodically have a third party — a lead, a peer team, or a structured tool — re-score a handful of already-decided candidates. Drift happens gradually; a quarterly spot-check catches it before it compounds.
