When were the mass interviews? I would say that if they're going to interview you, then there are still jobs left. I haven't looked at their web site lately, but some of the jobs I applied for are "on hold" according to my application status. Most of them the recruiter said I wasn't qualified for because I don't have health care experience.
Anyway, when I got the call from HR, I had a phone interview by Friday of that week, a manager contacted me the following Monday, I interviewed with her that Weds, and they made me an offer by Friday. It happened very quickly.
Good luck on the phone interview. It is very, very basic and she will ask you very general questions about previous work experience - how you got along with people, how you manage stress, things like that.
By the way, at HF, for the nurse intern position, you can't have license yet, and they expect to pass the NCLEX within 60 days. So if you get an offer, don't take your NCLEX before you start. I was hoping I could do that and get it out of the way, but the recruiter said not to - that they wouldn't be able to hire me as a intern and there are no positions for RNs with no experience!
So I guess I'm glad I didn't get my ATT before I figured that out!
