two interviews..two positions

Since my last post, I have been on two infection practitioner interviews with one company and just got a phone call for another with the company that I currently work for.

I would obviously much rather have the last job as I would keep my senority and pay grade. I come with no experience but great enthusiasm. I related my interest in getting certified and stressed my military background. I think I did well on the two interviews, with questions related to my attention to detail, organization skills.....anything you all can think of to help me nail the first interview with my current employer?

Background, the first company wants an ICP to be an offsite practitioner at an ortho surgery center and clinic. The second position is at a teaching hospital.

Thanks in advance.
