Some divergence in a debrief is expected—interviewers cover different competencies and will naturally have different assessments. But when one interviewer is a strong hire and another is a strong no-hire, and the competency assignments don't explain the gap, something else is going on. These are the top causes.
Interviewers vary in how well they surface evidence for the competencies they're assigned. A skilled interviewer knows how to ask follow-up questions that push past a polished answer and get to something specific and real. A less experienced one may get caught up in small talk, follow tangents, or drift away from the competencies they were supposed to cover—and walk away with a strong feeling about a candidate without the evidence to back it up. Different quality interviews produce genuinely different amounts of useful signal, and that shows up as divergent opinions in the debrief.
Sometimes the opinions aren't as different as they look—the feedback just doesn't capture what the interviews actually surfaced. Sparse feedback that says little either way, and impression-oriented feedback that focuses on personality rather than skills, can both make interviewers look further apart than they actually are.
Research from Textio analyzing over 10,000 interview assessments found that more than a third of interviewers had commented on a candidate's personality by the time that candidate received a job offer—and candidates who received offers were 12x more likely to be described as having a "great personality" than those who didn't.
When feedback drifts toward personality and overall impression, two interviewers whose conversations surfaced similar hiring evidence can appear to have reached completely different conclusions.
When feedback is thin or impression-based, the debrief can quickly become a discussion about how people felt rather than what they found. That's where divergent opinions tend to calcify—because without shared evidence to refer back to, there's no way to resolve a disagreement except through advocacy. Whoever feels most strongly, or speaks most confidently, tends to drive the outcome.
The first move in a debrief where opinions are far apart is to get specific: what did each interviewer actually ask, and what did the candidate actually say in response? That question often reveals whether the divergence is rooted in competency evidence at all—or whether it's being driven by personality, likability, or an overall impression that formed independently of what was assessed. If interviewers struggle to point to specific candidate responses that explain their read, that's usually the answer.
Also, go to the source: recordings or transcripts from each interview can make visible what the feedback didn't capture—whether the conversation stayed on competencies or drifted, and whether the strong opinions in the room are backed by anything specific the candidate actually said.
