Hello/need interview info

Hi! I'm new to this site, and I am hoping to get some helpful advice and information. I have applied to the Tennessee Technology Center and taken the entrance exam. I have to attend an interview next. Can any of you give me some advice? What is the best thing to wear? What is the interview like? How can I prepare?

At my entrance interview..I wore sort of casual/formal wear. Black pants and a pretty sweater with some dress shoes. My DON asked me why I wanted to become a nurse, what my best accomplishment was in life, if I had any expierence in the nursing field, how did I do in high school, did I like to work as a team member, etc. Just be calm, answer the questions in a timely manor, and don't get nervous =)
