Phone interview was the first type. I spoke with, primarily, the Engineering Manager at the time. We discussed the basics of the job, which is very very generic. Expected ("typical")) working hours, location. Second interview was in person. My colleague had been there for a couple months by now so he gave me a tour of the production floor. I recall the HR and Engineering Manager being a part of this. A few of the same questions were fielded. A few of the benefits were discussed.
