TBH, you dont have to be great to get the job, just good enough. ive seen someone do a fairly crappy audition and get the job, because the way they carried themselves. Just be able to do some sort of scream,growl,etc.and you should be alright.If you have any questions, feel free to ask me.(Also, its kinda fun during auditions, and even more fun working, it almost outweihs it when guests attack you, which the worse ive had hapen as i was spit on...)
