Why Sequence Matters
The debrief — the meeting where interviewers discuss a candidate and reach a decision — is where most of the bias in a hiring process actually occurs. Not in the interviews themselves, but in the conversation afterward. If interviewers talk before submitting their feedback, one strong opinion will anchor everyone else's.
This is called anchoring bias: the first piece of information you hear disproportionately influences all subsequent judgments. If the most senior person in the room says "I thought they were weak" before anyone else speaks, the junior interviewers will unconsciously revise their assessments downward, even if their own evidence pointed the other way.
Step 1: Blind Feedback Submission
Every interviewer must write and submit their detailed feedback — including a hire/no-hire recommendation — before any group discussion takes place. This is non-negotiable. The feedback should include:
- The specific questions asked.
- The candidate's actual answers (paraphrased or quoted).
- How those answers mapped to the rubric.
- A final recommendation with justification.
The feedback is locked before the debrief begins. Interviewers cannot change their written assessment after hearing others' opinions.
Step 2: The Debrief Meeting
Once all feedback is submitted, the team meets. The structure:
- Silent review (10–15 minutes): Everyone reads all feedback independently. No discussion yet.
- Discrepancy identification: The Bar Raiser identifies areas where interviewers disagreed significantly. These are the most valuable data points.
- Evidence-based debate: The discussion focuses on resolving discrepancies by comparing the specific evidence each interviewer gathered — not impressions, not feelings.
Example of a productive debrief exchange:
"Alice, you rated the candidate 'Strong Hire' on system design, but Bob rated them 'No Hire' on the same dimension. Alice, what specific answer led you to 'Strong Hire'? Bob, what did you observe that led to 'No Hire'? Let's see if we're looking at the same signal."
This kind of exchange often reveals that the interviewers were testing different things, or that one interviewer asked a follow-up question that exposed a gap the other missed.
Step 3: The Decision
The debrief ends with a decision. The options are binary: Hire or No Hire. There is no "Hire with reservations" or "Let's see how they do." The decision framework:
- Hire: The evidence clearly demonstrates the candidate meets or exceeds the bar for this role and level.
- No Hire: The evidence clearly demonstrates a gap in one or more required competencies.
- Ambiguous: If the evidence is genuinely mixed and the team cannot reach conviction, the default is No Hire. The cost of a false positive (hiring someone who underperforms) is almost always higher than the cost of a false negative (passing on someone who would have been good).
The "when in doubt, don't" principle is not pessimism — it is risk management. A bad hire costs 6–18 months of salary, management time, team morale, and the opportunity cost of the headcount that could have gone to a stronger candidate.
