Couple of online test; 5 hour simulation with 6 other applicants. Extensive process for an external candidate but great time to learn about the company purpose and weed out process.

Contacted through email, then phone interview. Next an onsite interview with a panel of 2 production managers and 2 HR personnel. The interview was behavorial based, which if you have plenty of S.T.A.R. examples you will be fine. Patience is key because they interview a lot of people, but they do a great job staying in contact with you through the entire process. Took 3 weeks before I recieved an offer because I was in the early wave of candidates.
