Is it a coincidence that my interviewer, one of many interviewers, happened to be an ophthalmologist—when I've had two years of experience working in ophthalmology? Hmm... It could be, but I don't know, that seems a little personalized to me.
I had a friend interview at this location as well, and she worked in a specific specialty; she was also matched to a physician in that same specialty.
This makes me feel like, at least at this particular medical school, the interviewers may be a little personalized.
