Hospital Hiring Process

I'm sure i'm not the only one here in this situation, but I've been putting in numerous applications into hospitals around my area, as well as some further away (I live in the Edison area) and still, I haven't recieved any call backs. I got some advice from one of my old teachers saying that the more apps you have in, the better chances you have of getting a call back. So I tried that, applying for the same position like 10 times, but still nothing. I also went over to RWJUH-New Brunswick, and they told me that it's usually two weeks before they get through all of the applications, then they call qualified candidates. I was just wondering, what is the best way to go about this? After putting in an application, I know it's always a plus to go in to HR for a follow up, but most likey, the hospital just tells you "We'll give you a call". By the way, i've applied to RWJUH NB, Rahway, Hamilton, JFK, Somerset Medical Center, RBMC. Any advive? Thanks!
