Dollar General Store Manager interview questions

I applied online for a posted position of "Store manager". Filled out the application, uploaded my resume, and within about a week I received a call from a district manager. He asked me a few question about my previous experience and why I left my last job, a few other basic questions,and then asked me if I'd like to meet for an in-person interview a few days later. I met the DM at a local store location. The interview took place in what appeared to be a small room that doubled as an office. As he began the interview, he said I see you've applied for the "Store Manager CANDIDATE" position...at which time I asked him to explain how that was different than the Store Manager position I had actually applied for. He explained that it was basically an hourly position in which potential store manager candidates were placed into, until a store manager position opened up. This was not what I applied for, but I continued with the interview to see if I could get more info. I wouldn't normally discuss pay expectations in a first interview, unless asked, but I had to ask what the hourly rate was. It didn't sound promising. I still expressed interest and at the end of the interview (which really wasn't a formal interview of any kind, more like a "This is what the general manager of a Dollar General does, do you want to do it"? session. After I had asked my questions, he asked me what I thought, and said I was interested pending what the hourly rate would be during my "candidacy" period. He said he would need to partner with his Regional Manager on a rate and would get back to me very soon, telling me he would call me within 2 days and said he looked forward to talking with me. That was the last I heard from him. I left feeling like the whole interview process, and possibly the operation was unprofessional, and wasn't disappointed that he never called me back in a way.
