Interviewed at the Davis Besse Plant (Oak Harbor, OH). There were 2 interviews. The first was a phone interview where they asked basic background questions such as year, major, willingness to commit to multiple coops, etc.
The second was at the actual plant. Spoke with 2 electrical engineers. Ran down my resume, asked about project experiences, why I applied, and a few behavioral questions. Afterwards they showed me around the plant. Very laid back interview. Showed me some of the plant. I heard back in a week.
