After submitting my cover letter and resume, I was contacted quickly for an interview with HR. It took about 40 minutes and was fairly relaxed. The second interview was a group interview where they gave us a quick scenario to go through together. After that they gave us a quiz and then did individual interviews where they asked mostly the same questions again, but this time with the individuals you'd be working with (lab manager, production manager, etc). This second interview took 1.5 hours.
