Metrics interviewers trust (and the ones that sound like hand-waving)

Credible metrics tie to decisions: what changed, why it mattered, and how you measured it without gaming the outcome.

Weak metrics sound like vanity: big percentages without baselines, or “improved performance” without defining performance.

Practice defending one metric per story under pressure using setup with harder difficulty.

Keep a “metrics bank” note per story inside your practice hub so you do not scramble numbers onsite.
