After submitting my resume to their careers website and emailing directly to HR (curiously you need to do both). they emailed me about a month later to set up a phone interview. The phone interview lasted about 15 minutes and was very easy. No difficult questions, just a quick review of my resume and discussion about what the company does. They rely heavily on internal recommendations (I had a couple of them) and I was told that they unless I did something really stupid, the job was mine. About a week after the phone interview, I went in for face to face interviews. The questions were very softball, hardly any of the standard "Tell me about a time when you..." type questions. I interviewed with a quality engineer, his boss and the director of the department. They were all very nice people and really interested in learning more about you, not grilling you by asking you question after question in a formal manner. The atmosphere was very relaxed and the workers seemed similarly relaxed. The face to face interview lasted about 2.5 hours.
