Interview for Residency Program

I am interviewing for a Residency program in DC this week. This will be my first interview since graduating from nursing school a couple of weeks ago, and I am really excited, as well as a little bit nervous. Can anyone provide any insight or advise as to what to expect? Is there anything I can do to be better prepared for situational type questions? I have been instructed to bring transcripts and letters of recommendations. Is there anything else I should bring to the interview?

Thank you in advance for your help.
