Counseling and Guidance MA interview

I have an interview for the Counseling and Guidance MA program at Cal Poly San Luis Obispo and I am really nervous! I am having a hard time finding information about their program besides what is on their website (and it is not very detailed). If I can't find any other information about the program, how should I prepare myself? I have already submitted a resume, autobiographical statement, and 3 references.

Is there anyone out there that is in a similar program that can give me some advice about what I should expect from the interview? What kind of questions were you asked?
