This is how my interview process went: 4 separate interviews; the first HR recruiter, 2nd Quality Engineer, 3rd current Supervisor and last the QA Engineering Manager. Overall the process was standard questions.

Very friendly staff and easy to talk to. Interview lasted about 1 hour, with a great tour of the factory. Interesting place, very busy and fast pace. I felt like I should put on roller blades to do the job, that way I could move fast and produce results.
