I'm assuming you know 'cuz of the website? Congratulations! Well I guess they do all of their scheduling by snail mail. I think they are going to send you something, you say what days are good and you send it back. Then they send a date to you. I am not sure though 'cuz I didn't deal with any of this 'cuz the lady called me the same day to see if I could come down immediately for an interview.
