What should my next step be??

I'm currently working PT in a local prison in a job that I enjoy but in which the DON was less than straightforward about when I started. I recently got a call from the nurse manager of the local hospital (large healthcare system) because she had received my resume back at a time when she had no openings but now has a few open positions. It's a job I absolutely want without question. In our conversation she told me that she received my resume from another NM who had pulled it from HR but had decided not to use. She instructed me to send my resume to HR again, she would call them and have them interview me per policy and then she would do an interview herself. I did as she instructed and the. Followed up with a phone call to her to let her know I had sent it. So far, nothing. Competition is fierce at this hospital and I was shocked to even get a call. I'm not sure what my next step should be. Any ideas???
