I'd like pose this question from Knife and Gun Club again because I've had similar experience with my interviews. Generally have come in to the room, maybe answered a standardized question without much difficulty, and then talked about hobbies, then answer"why program X?", "where do you see yourself in 10 years", etc. then ask the interviewer a few questions about the program before ending the interview with a handshake. I generally present myself as genuine, engaged and upbeat and I can't really think of much else I could do to stand out. I assume most applicants are doing the same as myself and I don't quite understand how the interview can have such large implications for rank list unless an applicant comes across particularly poorly.
