In the interview he asks about how much experience you have in security, he asks where you've worked what you did there. Once he gets past the information about you, he begins to ask about your training and what they covered with you. He'll also ask about days you'd like off and tell you that you aren't guaranteed the day you want or need off and inform you that if there's something important you can apply to take that day off and hope it's approved. It's not a very stressful process, seemed fairly laid back.
