Regal interview questions

The Hiring Manager never called after putting in an application, it took several calls to even get an interview and when I finally got ahold of the hiring manager she seemed to not even know that I had put in an application and looked at it right on the spot while I was on the phone with her. The interview itself went well, I think, I seemed to do okay but now I'm stuck waiting to know if I got the job and it's been about three weeks since the encounter. I've called twice since but still no reply.

I walked in the day before interviews and talked to a manager (there are many different ones, this one just happened to be on the floor that day) he told me to apply online and when I told him I did, he told me to put my name and SSN on a paper, and he'd pull my application for interviews the next day, and to come professionally dressed with a couple of forms of ID. The next day I arrive a few minutes early, and I wait in the party room for the interviewer to come in. There were about 5 other people there. When the interviewer came in, he had everyones application but mine, so I guess the manager forgot to pull it. He went in order of who had arrived first, but even though I came before another gentleman, he didnt have my app, so he promised to still interview me but I went last. I thought I did a terrible job during it (since it was my first interview) but both managers were very relaxed and friendly, and at the end they gave me two reference sheets to fill out in case I was hired, and that they'd call me this weekend to tell me or not whether I got the job. I fully expected not to get a call, but three days later Sunday morning I got a call saying they'd decided to go with me, and to come in thats Tuesday with my ref papers for orientation. I got my ref papers filled out at school that day (im 17) came in Tuesday, wrote a definite schedule (the woman told us to make it as close as possible to what we put on our applications because its most likely the reason we were hired), and that was about it, we came in the next two days for training, and I officially started that Friday.
