ASM NEXX Software Engineer Co-Op interview questions

The interview was a three hour on-site. I got a tour of the facility, including the lab, which is a clean room requiring a gown that they provide. They took me to lunch with a couple software engineers from the company, then I got to talk to some other engineers when we got back after lunch, mostly about things on my resume. Lastly, an engineer gave me a few technical questions and one whiteboard coding problem. Everyone was friendly and hospitable.
