Sorry to jack your thread OP, but is it OK to:
1. Not say the person's name when concluding the interview by saying thank you and good bye, in fear of saying it partially or completely wrong?
There is an old saying that people love to hear their name and using their name in a hello and/or goodbye is good. That said, if you think you'll mess up the pronunciation, skip it and it will be fine.
On the other hand, do not use your interviewer's first name!! I saw some applicants criticized harshly in the interview write-ups for calling middle-aged female physicians by their first names.
😱
2. Call the admissions office prior to the interview to ask who your interviewer will be, if you were not offered that information in the first place?
I'd take this as a little creepy... as if you wanted to cyberstalk them before the interview. At my school, anyway, the assignment of interviewers is made <24 hours before the interview.
Bottom line, ask for a business card if the name isn't provided to you in writing on interview day. With the name, you can find the email address and often snail mail address very easily through the university/medical school directory available online.
Thank you notes won't improve your chances of being admitted. I think that I got 'em from 40-50% of the people I interviewed and they ran about 50-50 between email and snailmail. The snailmail was usually in the form of those little 'thank you' cards that you can by in packs of 8-10 from Hallmark, etc.
In one case, I got a cute blank card from the gift shop of a tourist attraction that I'd discussed with the applicant.
