The hiring process took 3+ months. I submitted an application in January. Heard back from HR a few weeks later who had me fill out a questionnaire. About a week and a half later I heard back from HR again who scheduled a phone interview with me. The questions were mostly about my experience. About a 2 weeks later, I was brought in for an interview with the managers I'd be working with. This was a series of 20 minute interviews with a bunch of managers in the department I'd be working with. Nothing they asked me was too tricky, mostly questions from my resume. The whole process has been a positive experience so far and the HR woman who has been dealing with my hire has been extremely professional and really helpful through the whole process.

Phone interview with hiring personnel from a different office. In person interview with office manager. Second interview with a project manager. All three were simple, easy-going interviews. They want someone they can talk to easily. Just have a conversation with the person on the other side of the phone/table and you will do just fine. Be friendly, polite, and don't be shy.
