Wow! First few interviews!

I just graduated from a two year RN program and am scheduled to take my boards on July 16th. I am an LPN. I've had three interviews so far for three different hospitals. One in CO. and two in CA. My firt two went great and I have basically been offered jobs. The second interivew at an OC hospital this morning was terrible! I sat down with the Dept. Director, a charge nurse and another RN. The interview started out well and it was the basic meet and greet type questions. Then the DON starts giving me case scenarios about ortho patients etc. What would you do if you saw this. No big deal I thought. I said I'd assess the patient etc. She wanted more detail in my answers i..e walking her through my head to toe assesment. One of the case scenarios was a patient with a PE. What would you do? What would you order yadda yadda? How is a PE diagnosed. At one point she asked me how much O2 I would put the patient on (who's sats were 88%) I said I'd probably start them off on 1-2L. She said well that probably wouldn't do much you'd want to try 4L or so. Anyways, this was the worst interview I've ever had. I felt completely off guard and had no idea I would have to answer questions like that. I have a feeling it was because I was a male and had a 2 year degree. After the interview she said that she didn't think I was a good fit for her floor etc. I was upset and yet so angry. I've talked to other new grads and they've never had an interview like that. Maybe a question or two like what would you do if you walked into a room and saw this or that. But nothing like what would you order, detailed assessment questions, diagnosing PE's etc. I mean is this normal? My other interview was much different. At the other hospital in OC the recruiter interviewed me and showed me the hospital, handed out my resume to charge nurses on the other floors, and said when I get settled to call her and set up a second interview with a charge nurse on a specific floor. Anyone else have this experience? I want to call the nurse recruiter at the hospital and tell her what a negative experience I had and if all the interviews are like that and all the floors?
