I guess it depends. In one job I gave my feedback in a nice way that didn’t put blame on people but procedures and it helped the remaining coworkers.
In the another job I didn’t think providing any kind of feedback would help me or anyone there due to multiple reasons, so I didn’t even try.
My experience has been that people (including me) kinda suck at accepting critical feedback. You could try to mitigate this with some techniques but you never really know how the receivers will take it (or how the message is relayed!!) So the rational thing to do is to play it safe and not do an exit interview unless you are sure that it won’t backfire on you.
