>"I don't feel like I'm a fit for <xyz> company"<p>This is a really good general cop-out answer because it avoids creating hard-feelings or burning bridges if there was actually a more specific complaint (I hate working with that guy, my manager sucks, the work is super boring, product is stupid, pay sucks etc.)<p>First thing to check is, where the person is next going, are they going to be making more money? If so that is likely a reason. Another reason could be that they thought their potential for advancement at your company was low, at least in comparison to somewhere else. If the employee is an engineer, it could also be that they thought their learning had slowed or they were not working on the right kind of tech they wanted to for their career. For me, these career related reasons are the most likely reasons I would jump ship.<p>It's important to note that you shouldn't take a career-motivated jump personally. The only thing you can do is try to reorganize your company to make this less likely, by paying more, giving more opportunity for advancement, or working on/with sexier tech.<p>If it's not about career, it's probably either interpersonal or cultural. Maybe they feel socially excluded? Maybe their manager is too distant, an asshole, or a creep? Maybe they don't want to work as long / the same hours as everyone else?<p>Regardless, there is a very good chance you will never get a straight answer, or will get some fake, nice excuses. This type of thing requires introspection, not an exit interview.
