Apply online and a recruiter will call you. After your phone interview you'll be interviewed my management and the head of the site. If they both like you, you're in.

Just walk in like you own the place. Have high confidence, be dressed to kill, perfect hygiene, etc. Ladies, I recommend a dress with heels. Guys, absolutely wear a tie, if possible a jacket as well. They don't care about what you know. They care about how you look and how much personality you have.
