This is for those of you who want to audition but have never done it before:
Don't look at the judges when you are reciting your monologue or singing your song.
If you have a sad monologue then use a happy song.
Be pleasant, not cocky, not nervous, just pleasant.
Try not to ask questions in your monologue, unless it's to your own character.
Relax and maybe even lie down before your audition just to find your "special place" (my special place is a small island with a 3 palm trees)
If your monologue is to one person, look above the judge and have one focus point, two people: Look about five feet to the left for one and five feet to the right for the other, three or more: same as the second but with one in the middle "but what if your character is talking to a crowd?" You'll look like an idiot moving your head everywhere, three is the magic number.
Don't just stand there when you sing your song, add slight character movements (Example: Trololo, seriously, if your song is happy, look happy and gesture happily, if your song is depressed, be sad about it. Also, my personal problem is that I tend to lower my eyebrows when I focus while singing. Don't do that.)
Callbacks are bloodthirsty underneath, don't worry about one-upping someone because it will happen to you.
That's what I use, you don't have to listen to me though, try your own technique.
