Consultants charge thousands to tell you why staff leave; your leavers tell you free, in their final week, with the candour of people who no longer need anything from you. Most employers skip the conversation - too awkward, too late to matter - and keep paying tuition for lessons already delivered. The exit interview is twenty minutes of structure that turns each departure into process improvement.
- Leavers are your only informants with nothing to lose - and most employers skip the conversation entirely.
- The gold is in patterns, not individuals: three exits mentioning the rota is a diagnosis, not a coincidence.
- Ask about the job's reality versus its advertising - the gap is your hiring-process feedback in its purest form.
- Exit tone writes reviews, powers boomerang rehires and referrals - the last conversation compounds either way.
Getting the truth: setup matters
Three design choices unlock honesty. The asker: not the direct manager - who may be the reason - but the owner or a neutral lead; leavers protect relationships to the door. The timing: final week, not resignation day - emotion settles, reflection sharpens. The frame: 'you can help the next person' converts venting into advice, which is the register you want. And listen in negative space: what a warm leaver conspicuously does not mention is often the finding, per the reference-check listening skill.
The six questions and their routing
- The trigger question ('what made you start looking?') feeds your turnover diagnosis - triggers cluster far more than exit-form categories suggest.
- The promise-gap question ('how did the job differ from what we advertised?') is your hiring audit: gaps here mean the ad recruits people the job then loses - rewrite per the template's honesty rules.
- The retention-price question ('what would have kept you six months?') prices your fixes: often it is the rota, the review that never came, or twenty cents - all cheaper than replacement, per the true cost.
- The screening question ('what should we ask your successor's candidates?') upgrades your knock-outs with expert testimony.
- The keep-doing and boomerang questions bank the goodwill: strengths named, door opened - alumni rehiring is the cheapest experienced pipeline you have, per past applicants.
Patterns, not postmortems
The individual exit is weather; the quarterly sheet is climate. Log role, tenure, trigger and promise-gap per leaver, review quarterly, and act on anything mentioned three times - that is a diagnosis wearing a coincidence costume. Tenure patterns speak too: week-three exits indict onboarding or the ad's honesty; month-eleven exits indict the missing raise or ladder; a manager's team churning at twice house rate indicts the manager, however good their own numbers look.
The takeaway
Twenty minutes, six questions, a neutral asker, one running sheet, quarterly pattern reviews - and every resignation starts paying you back in fixed ads, sharper screening, saner rotas and returning alumni. The staff who leave are the consultancy; the discipline of asking is the fee.
Close the loop.

Do leavers actually tell the truth in exit interviews?
More than anyone else in the building - but conditionally: honesty rises when the interviewer is not the manager they may be leaving (the owner, or another site's lead works better), when the conversation happens in the final week rather than the emotional resignation day, and when the framing is explicitly forward-looking ('help us fix this for the next person'). Even then, expect politeness bias - read what is conspicuously not praised, the same negative-space skill as reference checks.
What questions actually produce useful answers?
Six cover it: What made you start looking? (trigger, not story) - How did the job differ from what the ad and interview promised? (your hiring feedback, pure) - What would have kept you six more months? (the price of retention, stated) - What should we ask the next candidate for this role? (screening advice from the expert) - What did we do well? (keep-doing list) - Would you come back, and for what? (boomerang door, opened). Twenty minutes, notes taken, thanks given.
What do I do with the answers?
Log every exit on one sheet (role, tenure, trigger, promised-versus-real gap, retention price) and read it quarterly for patterns - single exits are anecdotes, three matching ones are a work order. Route each pattern to its fix: promised-versus-real gaps rewrite your ads, availability collisions rewrite your screening knock-outs, rota complaints go to shift planning, manager patterns go to a harder conversation. The loop closes when the next quarter's exits stop mentioning it.
