I have a job interview, any tips?

I haven’t had an interview for a while. Every interviewer is different. I got my first job because I didn’t “pester” the person hiring with phone calls. Lucky, no? I’m applying at other places while I’m at maybe get a couple part time jobs.

I have a job interview today at a movie theater. It isn’t one of the big ones. You sign up on a list and get an interview later that day. Are there any things that I should definatley do? Questions I should ask afterwards?
