LOL don't waste time preparing. They'll hire anyone. You could probably waltz in still half drunk and hung over from the night before and they'll hire you on the spot unless you do or say something overly stupid. Pretty much just show up dressed like an adult and they'll throw a job at you. Don't worry about knowing someone or thinking you have to network your way into this place. They treat people so badly and turnover is so high that even while having their yearly layoffs they still hire.
