Interview TOMORROW! HELP!!!...

Okay I faxed my resume and cover letter for a Case Manager position last week and got an email today requesting an interview tomorrow. The position actually asked for an LPN or Social worker with experience, but I guess a new grad RN (who hasn't taken NCLEX yet) was good enough to get an interview. I also took two case management CEU courses last month. I have been looking for a position where being an RN would be favorable but not required since I refuse to even apply for NCLEX until I know that I will pass with 75 questions, and I need a job now. And on top of that I like case management.

Anyway I am a little scare because this was such short notice. Also I don't know if this will be a panel interview or what. Please give me all of the tips and advice you have.
