You basically just do your part of the sequence that the management team wants you to do (if you're auditioning straight out of the YTT experience). Otherwise, when auditioning for other management teams that you're not too familiar with (like if you move cities), you just do a sequence of your choice and they assess and evaluate your abilities from there.

Its typically a group audition with a panel of experienced instructors and management. They give you about 5 minutes to teach a portion of a set sequence to see how you hold space in the room.
