Like most of the interviews described here, the process was pretty straight forward and designed in a round robin style. There were four interviewers and each had an allotted time of 30 minutes to come in and speak with me. In my opinion, it was pretty smooth...no behavioral questions or "tell me about a time". Instead rather it was pretty much explain to me what you've done and how that can contribute to the team we're hiring for. Additionally, my interviewers wanted to make sure that you were a good match. For example, if you're not interesting in workforce planning and that's their main project type then obviously it wouldn't be a good match. The best advice I can offer is to (1) know your resume, and (2) ask lots of questions.
