To be fair, it wasn't that awful in my experience. The questions were standardized and my interviewer was definitely trained to have a poker face, but I do agree that I wish it was more conversational. There is ample opportunity throughout the interview day to ask questions, maybe even too much time to ask. The vast majority of the staff and all of the medical students were extremely friendly and really honest about the school, which is rare to see in interview q's/a's. The medical students were the highlight, I got more information through them than anyone else so please make sure to ask any burning questions you have.
The long breaks between the different parts of the interview day was the most confusing/tiring, that was the only issue I had personally.
