My interviewer at the school I currently attend only asked me one question: “What do you love most?”
It was certainly very interesting, and while it caught me off guard, I believe it really did help me express myself far more effectively than I could have in my other interviews. It was one (of many) factors that really made me fall in love with the school.
It appears, however, that that’s his specific “gimmick,” as I spoke to some of my classmates and most of them had fairly generic interviews, but those who were interviewed by him had the exact same experience.
