Haunt acting audition tips??

Hey guys!! first off let me say i love Halloween. I'm literally counting down the days. i live in saint louis and auditions are being held at the darkness for positions as a monster there and at lemp brewery.

I have a few questions of course because I've never worked at a haunted house but can a noob like myself have a chance??

I have created a few characters that I want to act out but I'm having trouble deciding which one. What do they really look for when hiring actors?? Anyone got any valuable tips? All help would be appreciated. Thanks a bunch <3
