I was interviewed by a faculty and a 4th year student. My advice would be that you should visualize that you are actually going to attend the school, that will help you feel more passionate about the school and just keep your cool. Definitely go on their website and read as much as you can and mention the things that you read about, ask them about the programs, that shows them that you really care about the school. The whole day was pretty chill. I am the type of guy who freezes up in public, but I think it was a miracle that I was interacting so well with the people there. Wings and pizza--awesome.
