Have you worked at Hot Topic? Questions about the job?

I'm applying for a job at Hot Topic and would like to know what it all entails. I'm extremely nervous on getting a job because this would be my first job ever. What do the people who work there do? Stock the shelves? Cash people out? What all would I be doing if I got it? I'm just applying for a sales associate. Not a manager or anything. Please give me all the information as possible. I want to be prepared.
