Need information about program coordinator job offer?

Hi, my name is Brant and I got a call for a job interview monday for a program coordinator position. I want to find out what exactly a program coordinator is before I show up. I am guessing she called me either because she knows who I am, or it could be because I have eight years social services experience. My highest level job was 4 years as an overnight residential counselor at a treatment facility. However, I did spend alot of time on the internet researching social rules and regs during my overnights. I did put that I have am comfortable handling both clients with no behaviors to clients with extremely violent behaviors. My focus was disability law. So if anybody wants to give me some data or advice that would be appreciated. She also liked my spasticgamer@gmail.com address too. That got a laugh.
