I'm no phyciatrist, and frankly I don't trust them half as far as I could throw them. If they're doing their jobs though, they look for how you react to situations, making eye contact, how you present yourself, ect.
Right now AS is in the spotlight, show any symptoms at all and they'll tell you that you have it. Don't focus on it too much, alright. ^^ Oh, and welcome to wrong planet.
