I was interviewing candidates for an associate role. I found that the candidates were doing very well in the interview and most of them were very well behaved compared to candidates from another college. Then at the start of the interview there was a candidate who was being too professional. To which I commented "The institute has trained them very well" in a light humor to the other panel members.
He felt I was rude, because even after getting shortlisted for the role, he said he didn't want to continue and without giving much of a reason, he left. Was I rude to say that? And how can I correct it?
