Apply online, pick a date to audition, show up, do light paperwork, get called into room to quickly audition (this weeds out bad actors), do a more intensive audition (act like I'm being attacked, act like the attacker, scream, etc.). After they let you know you've been hired, the training day consists of presentations about Universal's culture, what is expected, how the event works. All of HR issues are covered well. You sit at a computer to complete your hire-on process, get your picture taken and are told when to come in for a costume fitting.
