I'll tell you what I didn't say at the interview. I didn't ask about strengths/weaknesses or many subjective questions. For the strengths/weaknesses, I had my own criteria and asked in a way that required cold hard facts. How many pedi-hearts? Lung Tx? Both echo and nerve stim methods of regional anesthesia? Number of regional blocks? Number of elective months? Number of residents doing well enough on the ITE after CA2 to pass it for real? Etc, etc. I know that the program meets the minimum requirements, but I want to see what else they have to offer. I had many an interviewer tell me that they were refreshing questions and were glad that I was not another applicant asking them strengths/weaknesses for the 50th time.
I felt that asking the interviewers things like how well they get along with the surgery teams, how well residents were prepared by graduation, if there's head-butting with CRNAs, etc, were all pretty juvenile questions and did not ask them. Any interviewer would answer positively, but they cannot back it up with facts like my previous questions. I'd hear applicants ask these even at the end of the interview season. If you are compelled to ask, then ask the residents instead. You may get a more truthful answer and not look as silly in front of your interviewer.
