This is separate from telling your manager you're leaving
An exit interview is a distinct, usually more formal step run by HR or a senior manager, separate from the initial conversation where you notify your direct manager. Handle both professionally, but understand they usually serve different purposes.
Your reputation follows you past the last day
How you show up in an exit interview can shape reference checks and industry word-of-mouth well after you've left. Staying calm and constructive to the very end protects a reputation that took years to build.
Frequently Asked Questions
Can I decline to do an exit interview?
At most companies it isn't a legal requirement, just a common practice. If participating feels uncomfortable, it's reasonable to ask HR whether a brief written response could substitute for a conversation.
Could what I say in an exit interview come back to hurt me later?
Depending on what's said, it can end up in an HR file or get referenced in a future reference check, so it's safer to avoid emotional accusations that aren't clearly backed by facts.
