Interviewing for Trauma Unit

Hi fellow Nurses!

I am a fairly new grad (December 2010) who has worked PRN psych for a year. One position at a psych hospital with medically cleared patients and another at a hospital on a geri psych floor, involving medical needs as well. After trying for a year to get an interview on the Trauma Unit where I did my practicum, I finally have an interview next week. What kind of questions should I expect at an interview for this type of position? I know that I will need my critical thinking skills and a lot of energy for this unit, as well as good organizational skills and compassion. If anyone has any suggestions, I would really appreciate the input. I have waited so long for this interview I want to make a good impression. Thank you!
