NYU Candidate Day

My NYU candidate day is coming up and i'm wondering if anyone could share any advice or their input on the group interview aspect. I've never done a group interview and not totally sure what to expect. Are they going to ask true interview style questions and everyone responds one by one, or is it sort of up to you to jump in with a response and make sure you're heard? I saw some people saying its really more conversational, but I worry about being able to speak at the right moments if there are several people trying to make sure they stand out. Can anyone say what type of things they might ask, how many people are in these small groups, or any other advice on how to prepare??
