1) Do you audition in front of the producers, or in front of a camera
When you arrive at the auditions everyone is separated in groups. Each group is then questioned by a producer, they are asked to "sell themselves".

2) What sort of questions do you get asked?
I believe you aren't asked any specific question, just pretty much to "sell yourself".

3) Do must people take friends to just "tag along"?
I don't know many people, or heard any stories of people going by themselves.
