I prefer stay interviews to get feedback while people are still employed. But exit interviews are a good tool for gathering information from people who are leaving to improve retention in the long run.
Attached is an Exit Interview template that can be used or adjusted for this purpose.
Do you do exit interviews currently?
Any questions you would add?
