Recently I was offered a job at a company but I declined it. One of the biggest reasons for this was an unpleasant interview by someone who would have been a senior coworker. I heard that this company sends out surveys to applicants regarding their process. Usually with things like this my instinct is to not burn any bridges and to just lie and say everything was great (I assume that when they say "anonymous survey" they mean "anonymous until we want to look at who submitted it"). I also don't want to make trouble for that interviewer, but at the same time they were basically the reason I didn't take the job. Is it productive to say that on the survey? I'm not sure what the company would even do with that information because it's not like they'd fire the interviewer for this, and if they're a symptom of company culture rather than a cause, it was good to know in advance rather than after I accepted the role. This is all in the US.
I would really appreciate any insight on this, both from the perspective of if I'm hurting myself in the future by being honest and if it's a waste of time to try to give honest feedback. Thanks
