I'm going to be interviewed soon for the university I want to enroll in. They aren't going to see any of my grades, my SAT, or anything about me at all. So it's important that I make a good impression on them (about four people are going to be interviewing me).

They're going to be looking for enthusiasm and your ability to handle stressful situations most likely. I need tips on basic stuff: Should I come in smiling? Should I shake each person's hand while saying "Hi." "Hello." "Nice to meet you." etc.? What should I wear?

Also, I don't know what kind of questions they're going to ask me.
