>>15321545 There's gonna be physical challenges so if your an unathletic fatso you might not make it.
There might be an interview type of thing, prep a one minute introduction of yourself "Hi, I'm anon I'm this old from there, I want to be a wrestler because its been my dream since age 7 and I want to see if I can make it and if I can learn to hang with the pros" type of deal you'd do for any job basically except you don't have to lie why you want to be there. Practice doing it for a camera, maintain eye contact as much possible to the camera and interviewers and try to relax.
Talk to other people in there. Stay cool, stay relaxed, get to know people and be social. This is also part of the try out that you can work with others.
There maybe some acting so prep a character - this isn't gonna be a be all end all character but use something you are familiar with, a job, a topic, to base it on something more natural to you and your personality rather than for example trying to be Rick Flair -clone.
prep a some sort of 1 minute promo in character as a face and heel promo of the same length, and practice for example calling out an opponent to a certain type match type of promos and try different ways and moods to do the same two promos - do it excited, do it ominously and so slow it's uncomfortable, do it to beat, do it dismissively. This way your not dumbstruck if they ask you do something you didn't practice by heart.
Record yourself doing them, get comfortable being in front of a camera and being recorded. Wave your hands too, be animate, be alive.
