You are told the process over the phone, when they schedule the interview. It starts with a group interview where you introduce yourselves to the group, almost like a first day of class get to know you activity. Then applicants are given toys and the opportunity to "sell" them to the management and other applicants and "upsell" other items to go with the product in a presentation setting. They will then take select people aside for a one-on-one interview, in my experience, the job was offered on the spot.
