My initial communication was by phone and answered some interview questions. I didn't hear anything back for several weeks, but I kept calling to inquire about the position.
Then I finally received a call for an interview which took about a month.
Interview process went smoothly - first with someone I would be replacing and then I was interviewed by my boss. He was very easy to talk to and explained the position clearly.
It took another 2-3 weeks before I heard back from the HR department offering me the job.
