Unless you have been told you are not getting a role, it makes no sense to say anything negative about the process. Once you have been told you did not get the role, then no negative feedback would be given as it would seem its just because you didnt get the job. Only people with no stake in getting hired or keeping their job would give you honest feedback.
Good point 🙂
Perhaps I should launch an anonymous survey
FWIW it was all unsolicited comments, hence my taking them at face value.
Getting any kind of meaningful feedback for anything is hard, but still worth trying...
