I went to an open audition advertised on their auditions website. There were between 300-400 people, and to my knowledge about 30 of us were hired. The audition consisted of three rounds and after the first two were completed, the casting director made cuts. After the third round, they excused us all for the day, telling us those still in consideration would be contacted that night with information regarding a callback audition the next day. I received the email and attended the callback with maybe 70 or so other people. We did a couple more audition activities (no cuts were made) before being excused. I was emailed with a job offer later that week.
