I worked for a large company in a non-HR role, and have recently decided to move on to another job. In the middle of my transition, my direct supervisor was made a key figure in HR in addition to their original role, and opted to perform my exit interview.
This influenced what I said in the interview, away from what I originally wanted to say. I have heard that other colleagues who have previously left this company left negative comments about this person.
Is it a normal situation to be interviewed by your direct supervisor? Does this constitute an ethical problem if they were part of the reason for your leaving?
This company is not a start-up, and is in the United States.
