Auditions are pretty much every actor's least favorite part of the theatrical process. It's the stressful and anxiety-inducing first encounter with the director before developing the script into a fully-staged play.
For these actors, it's usually also the last.
1. The one who already read, analyzed and wrote a dissertation on the play
Sure, you should read the play ahead if you can, but is it really a good idea to come into an audition with the character completely figured out? After all, there are probably some things about the character you'll learn along the way if you're cast -- some you might never quite know for sure. And acting like you've got the play all figured out definitely won't impress the director -- it'll just make them think you can't take direction.
On the other hand:
2. The unprepared one
"Who is this character?"
Everyone else is here to audition, too. Most people's audition process does not include wasting their time explaining to you what you should already know. On the other hand, if the director didn't make the play accessible to you, then they probably wanted you to go in cold anyway, so stop trying to figure everything out five minutes before you're called.
3. The one who wants everyone else to shut up
4. The indecisive one
"OK I know she's upset, but like, how upset is she?"
JUST MAKE UP YOUR MIND!
Directors cast actors who take risks -- not actors who need instruction to even get through an audition.
5. The one who really "needs" this part:
The director more than likely doesn't care about how badly you want the part, nor do they care that the character "speaks" to you. They just want to see what you can do with the material you've been given. So, hush up and do what's been asked of you.
