Cash application specialist at a hospital

I'm interviewing for a cash application specialist at a local hospital. When I read the description it's basically accounts receivable. I'm curious on what that usually pays. I'm in Kentucky. I make 15 an hour working at Lowe's and there isn't a path to promotion or making more money.

I have hotel front desk experience quite a few years of it, and I'm going to school online for business management.

I'm looking for tips on how to land the job with this interview.
