The Exit Interview Asks the Wrong Questions
Exit interviews ask why people leave. Nobody asks what they know. Why the one meeting with a leaver misses the handover, and what to hold instead.
An exit interview asks one question in many forms: why are you leaving? It is a fair question. In most companies it is also the only structured conversation held with a person who is about to leave. It never asks what that person knows. So the knowledge of how the job is done leaves on the last day, and nobody wrote it down.
What the exit interview is for
The exit interview is a retention tool. HR runs it, usually in the final week. The answers are collected across many departures and turned into patterns. Pay, workload, a particular manager, a lack of growth. The patterns go to HR leadership, who use them to keep the next person from leaving.
That purpose is useful. It is also hard to achieve. Everett Spain and Boris Groysberg studied exit interview programmes for Harvard Business Review in 2016. They found that too many of them "fail to either improve retention or produce useful information." Their advice is about doing the retention job better: better interviewers, better questions and data that reaches the leaders who can act on it.
None of this is a criticism of exit interviews. They are built to learn about the company from the people who leave it. Keeping what those people know was never part of the design.
The question nobody asks
Consider what the successor will need in their first month. The recurring deadlines. The real approval routes. The customers who need a phone call before a price change. The problems that are half solved. The judgment calls that come up every few weeks. Together this is the institutional knowledge of the role.
The person who knows all of this is sitting in the exit interview. They are answering questions about their manager, their pay and whether they would recommend the company to a friend. Then they leave.
The two needs do not fit in one meeting. The exit interview serves future departures across the whole company. A knowledge interview serves one person: whoever does the job next. The two have a different purpose, ask different questions and serve a different reader.
It also comes too late
Even as a retention tool, the exit interview arrives after the decision. Gallup reported in 2019 that 52% of employees who left voluntarily said their manager or organisation could have done something to keep them. And 51% said that in the three months before they left, no manager or leader had talked with them about their job satisfaction or their future. The useful conversation never happened. The exit interview is the one that happens instead.
For knowledge the timing is worse. The final week is taken up by goodbyes, admin and a person who has mentally moved on. Asking them to reconstruct years of work in 30 minutes produces a thin summary. Much of what they know is tacit knowledge. It comes out in pieces over several conversations, because people remember things between sessions. That needs weeks, and weeks are only available from the day notice is given.
Why adding questions does not fix it
The obvious fix is to add a few knowledge questions to the exit interview. It rarely works, for three reasons.
The wrong interviewer. HR can record an answer about month-end reconciliation. It cannot tell whether the answer is complete. The right interviewer knows the work: the manager, or the colleague who will absorb it.
The wrong setting. In an exit interview people choose their words about their manager with care, because they know it will be recorded. A knowledge interview needs the leaver to say plainly which colleague really approves things. Those two moods are hard to hold in the same hour.
The wrong output. Exit interview answers are aggregated into themes. Knowledge has to stay specific and end up in a document one person can use. Once an answer is turned into a theme, the detail the successor needed is gone.
What to hold instead
Keep the exit interview. Keep it short and let it do its retention job. Then add a second conversation with a different owner and a different aim.
Start at notice. The day someone resigns, book two or three sessions of about 45 minutes. Hold the last one at least a week before their leaving date, so there is time to write it up and check it. The free Handover Kit has the booking email and a template for the write-up.
Let the manager own it. Or the person who will take over the work. HR can make sure it happens. The person who runs it must know the work.
Ask about the job as it is actually done. Cover the four kinds of knowledge that leave with people: what is written down, how the work is really sequenced, who to call and the judgment calls. We have collected 42 knowledge transfer interview questions grouped that way. Pay special attention to the agreements nobody wrote down, such as the check that happens before a quote goes out or an approval that goes to someone the org chart does not show.
Write it for the successor. Organise the answers by situation. What to do when the supplier is late. What to do when the numbers do not reconcile. Then turn it into the first weeks of role-specific onboarding for the person who starts.
A quick check for your own company
Answer three questions about the last person who left a key role.
Who was responsible for capturing what they knew?
When did that start?
Who has read the result since?
If the answers are "HR", "the final week" and "nobody in particular", the company ran an exit interview and no handover. The cost of that resignation is still being paid by the people who had to work out the job again.
Frequently asked questions
What is the difference between an exit interview and a knowledge transfer interview?
An exit interview asks why someone is leaving, so the company can keep others. A knowledge transfer interview asks how the job is done, so the next person can do it. The first is run by HR and read by HR leadership. The second is run by the manager and read by the successor.
Should companies stop doing exit interviews?
No. Exit interviews do a real job for retention. The problem starts when they are the only conversation held with a person who is leaving.
When should knowledge transfer start?
On the day notice is given. Several short sessions spread over the notice period capture far more than one long meeting in the final week.
What if the person has already left?
Interview the people who worked most closely with the role. After two weeks, ask the new person what they still cannot find out. The gaps they name show what the handover missed.
