As a supervisor in the OR, I get to participate and conduct plenty of interviews
The main thing that I look for is confidence and a TRUE DESIRE to work in the OR. Someone who is outspoken, pays attention, and seems excited for the potential position. We have been getting RN's right out of school who just want to 'try it out' lately... most of them quit within six months of hire, so we want to know that you are serious about this position.
I really stress confidence. We are leery about hiring quiet people... we want nurses who we know can stick up for themselves in tense situations, and can handle testy coworkers and surgeons. We want nurses who can work as a team, help others, and TAKE INITIATIVE in their learning.
As for questions YOU should ask, I don't know what the manager has told you about the position. A lot of questions we get is about orientation. A good question that we love to hear... "What do you expect of me as a nurse in the OR? What kind of qualities?" ....that's a gold star
Any other questions?
