I have a 'group interview' on Wednesday, any pointers?

So I really want this job and have already decided that I’m going to kick ass on the interview. I don’t really know what to expect though, being that this is my first ‘group interview’.

If it helps at all, the job is at The Container Store and I am hoping to become a personal organizer one day, which is where my confidence comes from.

Are any of you familiar with this interview style?

Bonus lurve for answers to “What’s your biggest weakness?”
