This WSJ article refers to a PGY-1's experience last year with Match violations.
I was asked multiple inappropriate (and illegal) questions when I was interviewing. (I was later told that one of my interviewers was taken off the roster because of his routine practice of asking unprofessional questions.) One thing I review with my clients in residency mock interviews is how to best answers these questions. I am currently scheduling mock interviews into the end of October, so please contact me soon if you are interested in my assistance.
