Started by talking to them at a career fair. Had an online assessment which mostly was pattern analysis, very tricky basic math questions, word associations and such but only had 15 minutes to go through 40-50 questions I think. Kinda rushed through it but still got a phone interview the week after. Lady on phone asked me some generic HR questions, how I heard about the company and why I'm interested in working for them. On-site interview comes after with a tour of the facility and potential supervisors asking you non-technical questions. Probably just one technical question throughout. I think its just them making sure that you like the company environment/culture first before thinking about the work.
