Process started with a phone screen, which was a resume walk through to determine whether you could hold a conversation as well as sell yourself. About a week later, and an extensive background application form, I was invited up to the Camas office. A flight, hotel, and car were booked for me and I arrived in WA a day before the interview.
Interview consisted of 3 rounds with different departments but the processes were quite similar. Behavioral questions, tell me a time this happened, give me an example of that, etc. As long as you can think on your feet, you should be okay. Know your resume, know your history, know yourself and you should be okay.
Last interviewer threw a curveball by asking a "what would you do" kind of question but because I had read other reviews on here, I was well prepared.
