ANOTHER person stood up and walked to the adjacent room, followed by the person accompanying him. That guy was already the 40th. With the auditionees walking to the adjacent room, the number of people in the waiting room started to dwindle.
Those who entered the adjacent room did not return to the waiting room. So, Astrid guessed that there must be another exit in the room where they were conducting the audition. He also observed that the time it took for another auditionee to enter the adjacent room after the last one was about six-seven minutes. With that, one could see that the time given for them to audition was only five minutes.
One might think that it was too short. But in Astrid's opinion, it's enough to showcase one's talent, if they were fit for the role or not. A competent actor should be able to show any emotions needed from him in just a snap of a finger.
