Hello! I just had a phone interview that I think went quite well, with a hospital that is across the country from me. The interviewer suggested that she would be interested in interviewing me in person, if I was planning to be on the area in the next 2 weeks. I am quite interested in the position, but I want to be somewhat confident in my chances before I spend $400 on a plane ticket. She said she will be conducting interviews for the next two weeks. It's possible I could buy the trip on Southwest, and they allow you to change the tickets with no fees, but it's still costly at this time.
Any suggestions on how I can follow up with the interviewer to make sure my chances are good before I make the trip?
ETA: I am a new grad who had a practicum in a related specialty to this position. I have been applying to many places out of my home state, where I am licensed. I have put out about 125 applications in 3 weeks, and this is the first interview I have gotten.
