Exit Interviews That Actually Produce Signal

Exit-interview research from CEB, McKinsey, and academic work on voluntary turnover converges on a sobering finding: most exit interviews collect polite, edited versions of why someone left. Redesigning them is one of the cheapest ways HR teams improve retention insight.

Why most exit interviews fail

• Conducted on the last day, by HR, in a single 30-minute meeting — too late, too rushed, too transactional.
• Asked 'why are you leaving?' — easy to deflect with 'better opportunity'.
• Single data point; not aggregated; never reported back.
• Interviewer is connected to the team that may be the cause — candor evaporates.
• No follow-up survey 6 months later when the real reasons usually surface.

The redesign

The question set

1. When did you first start thinking about leaving? (Surfaces lead time, not just trigger.)
2. What would have made you stay six months longer?
3. What did your manager do that worked well? What didn't?
4. What did the company promise that didn't materialise?
5. Where are you going and what is it offering you that we weren't?
6. Would you recommend the company to a friend? Why or why not?
7. What's one thing we should change before the next person leaves for the same reason?

Aggregation and action

• Aggregate quarterly by theme, not by team — protects anonymity.
• Report top-5 themes to the executive team every quarter.
• Commit to one structural change per quarter sourced from exit data.
• Close the loop in all-hands: 'Last quarter we heard X. We changed Y.' Nothing destroys candor faster than asking and ignoring.
• Track regretted attrition reasons separately — the patterns differ from total attrition.
