A debrief lands on hire, but when you read the written feedback every interviewer has vague evidence and nobody can point to something the candidate actually did. How do you handle it?

Treat thin evidence as a missing decision rather than a weak yes, because a hire made on impressions is a coin flip dressed as a process. Separate what was observed from what was inferred, find which required signals nobody actually tested, and close that gap with a targeted follow-up rather than overruling the room or rubber-stamping it.
