The interviewers were laid back. They want to know more about you and what your personality is like. Express interest, ask questions to keep the convo flowing. The tour of NYU is nice; as you tour, you can ask the current students questions about the curriculum, housing, and what to expect. I loved the food vouchers though. I also recommend wearing a piece of clothing or jewelery that makes you pop. It can be a tie with smiley faces or something that people will look in a room and notice you for while still dressing business casual.
