I went for many interviews, so here's my experience. They ranged from very scrutinizing to just a formality, ie, unless I started naked dancing in front of the NS, I got the job. There is a tendency for the private, more "prestigious" hospitals to be more selective. Be prepared for that, by recalling what you learnt about L&D, or what you know, and the usual "why do you want to be in L&D?" question.
Good luck.
ps. btw, if asked "what do you do if you are having problems with your coworkers that is affecting your job performance?", the answer is "go to the manager."
