Yep, theatrejock, pretty much. You're all in a holding room and go in one at at time (you'll hear the belters beyond the door, believe me!) Then when you come out, you are either smiling or taking "the walk of shame." She got a couple of hugs and said goodbye, quickly I might add due to my having packed up while she was "in there." There was a group of "callbacks" chilling together in the middle of the room congratulating each other and that's it... pretty much.
She just finished her last audition yesterday and said that PSU was the most stressful, partially because she loves the school, but also because of the process... All the teachers were in the room, along with many current students. You also had to listen to - and watch- the person go before you while on deck. Stress is

She did not, however, audition for CMU which from the posts sounds like an even tougher one.
Hope I didn't make you too nervous.
