You sit outside the office with other interviewees in a job fair like setting. One by one they will call you back and you will take different computer tests. A typing test, grammar test, and analytical skills test. Once you've scored high enough they will take you back and you will have an interview with the manager of the department you're applying to. After that, they have you meet with the Manager/Director of the office location. If he gives his approval then you will receive an email saying you're being considered pending a fairly lengthy background check.

Pretty straight forward, they asked for strength and weaknesses. I had a two part interview process, one over the phone with a recruiter and then a personal interview a few weeks later with the Department Manager.
