Well the interview was more structured than my other interviews aside from buffalo. I interviewed at michigan and case and ohio state's was more structured than those. You are interviewed by a fourth year student and an instructor. They alternate asking you questions. The only tips i have are pretty much the same anyone else would say... Be Yourself, don't fake anything. Be relaxed and social with them, but just answer the question because if you elaborate too much you may answer a question they are going to ask you later in the interview. Ohio State's interview/ visit was sweet. It's a great atmosphere, and they actually treat you like they really want you to go there, unlike some other schools i interviewed at. Just be all smiles and act genuine, and be polite. Have a good time, and good luck.
