Peer Interview

I am a new grad and recently had my first nursing interview and it happened to be at my first choice hospital (!!!). I went into HR for the first interview and that went great and then had an interview with the unit manager the same day. I wasn't as confidant that the second interview had gone as well as the first, but it must have been fine because they called me back a few hours later to set up a peer interview. Reality is settling in a little bit and I'm feeling pretty nervous. I can honestly say that I've had a lot of work experience in other fields apart from nursing and have a strong work ethic. I'm a very positive addition to any team and really love to work and help people and I get along with my coworkers. I know this about myself. Unfortunately, I am AWFUL at answering behavioral interview questions. I know I've had plenty of conflict resolution (was a security officer for 5 years) and leadership opportunities, but ask me to recall a specific instance and my mind goes blank. No matter how much I prepare for these and try to think of great responses before the interview, it always goes downhill at the interview. I think I psych myself out So, I'm worried about the eventuality of those questions and of course technical questions from the nurses. Any advice on how to manage without rambling on at an important interview?
