Practice but don't sound too rehearsed in your interview. I stressed about interviews so much but so far it really was nothing to stress about. I've really only had one interview where I felt like it was a real interview (situational questions, goal questions, how would you rate yourself on a scale of 1 to 5). It was fine though, the NM was very easy to communicate with. Good luck!
best advice is to have questions for your interviewer( will i have to work nights, do you self schedule, required holiday work vacation time etc....
(some say don't ask about vacation and holiday time but at one interview I did to find out that all vacation had to be scheduled a year in advance and you could only take 1 day during the summer and one day from november to jan 2nd. That just didn't work for me!)
, how is performace evaluated, how long is orientation, how many preceptors will i have (one place I had 8 different preceptors and that was NOT cool;.....find out as much as you can about the hospital (their mission statement etc) if you've had past experience know something about your previous employer.. I had one interviewer ask how many beds my previous hospital had (thank goodness I knew!) know how you view yourself, how you think others view you (I had a lot of questions like what would someone say about you concerning XYZ,
Talk with the recruiter before to get info about the hospital. One place i worked i had no idea i had to pay for parking until i was sitting in general hospital orientation. I also had no idea parking was as far from the hospital as it was, ask about benefits if they are going to be important to you, uniform
again good luck
