1 phone interview, 1 with HR, 1 with department head, 1 with shift lead, 1 with equipment engineering lead, 1 with process owner. No advice to give, it's difficult to describe the interviews, basically just be ready to talk about how you would fix their equipment when it breaks. For example, figure out what is broken, determine it is broken, order new one.

Had two interviews, both asked a lot of technical questions involving electronic schematics and instrumentation. First interview took about 20 minutes, second interview was about an hour. Very friendly and nice people.
