Dollar General interview questions

It took a couple of weeks to get a call back after applying. The manager called and requested for me to come in the same day. I advised I could not as I also work full time. She stated she would call me back another day. A week went by and she never called. I called to follow up and she was quite rude on the phone and acted as though I was bothering. I got a time set up. When I arrived for the interview the manager greeted me. She was very friendly. She did not really ask me any questions other than an open ended, tell me about yourself. She reviews pay, dress code, job function. She told me I interviewed well and she would call the store I wanted to work from and see of that had openings and would call me back on a week. I never heard from her. Called to follow up 3x and employees would answer the phone, put me on hold and never return to the line. I finally got in touch with her and she told me they didn't have any openings at the 2 stores in my town. Those stores still have "now hiring" signs posted.
