clintons cards group interview

Hi. I have a group interview at clintons cards tomorrow and was just wondering what questions could be asked. I have never had an interview before so what would it be like. Would i find out on the day if i get the job, or would they give me a ring?

Has anyone ever had a group interview with clintons? If so, what was it like. And what questions were asked?

Also how long would the interview take. And how many people are most likely to be there?
How can i stand out from the rest of them?

Thank you
