First, got one phone interview for an engineering position with group No. 1. This one was very basic and informal, and most of the time was spent chatting about the company itself, my previous experience, and the details of the job.
Second interview was on-site with group No. 2. After the phone interview they had apparently passed my resume on to a different group, but it wasn't exactly clear. The interview lasted for a full day and consisted of nine back-to-back interviews in the cafeteria, with a break for lunch off-site. I had to be escorted everywhere, even to get a coffee or to go to the bathroom, and saw virtually nothing of the company except the cafeteria and a conference room. They couldn't even tell me what I would be working on, beyond the most general or basic of terms. At the end of the day I was expected to give an hour long presentation on my PhD research. Exhausting.
Most questions were technical, like "can you describe how XYZ works," but there were also a few questions like "if you had a problem with a co-worker, what would you do?"
Portland is great, the pay would be good, but I was not impressed with the job itself. These people are expected to put in 60 to 80 hours a week, possibly more if needed, plus be on-call 24/7. And, since it's a huge company that makes very precise, reliable devices, the engineering jobs require extreme specialization.
The process engineering job interview focused heavily on real-world problem solving skills. They wanted someone who had lived in the lab, who had owned a tool, and had solved complicated experimental problems on it. Theoretical or academic knowledge was not a priority.
