PCT Interview: need some tips!

Today I got called for a PCT interview for a local hospital. I'm SOOO excited because I know it will provide LOTS of knowledge that will be so useful for me when I start in my nursing program this coming fall (that is, if they do hire me! *fingers crossed*). I was just wondering how these interviews usually play out; what kind of questions are asked, and what tips can you give me? What are your personal experiences with PCT interviews? I'm soooooo nervous and excited because I want this position so bad!
