An initial one hour video interview before being flown out for a site tour and in person interview. Entirely behavioral questions, but they rejected me before I was on the plane home.

All behavioral questions, not a single technical. I was flown out to tour the two plants in and had a panel interview with three people. Two were engineers and one was in finance. They were all friendly but asked from a list of questions that judged how well you could handle situations that are related to the job. Liked that I asked questions based off of what I saw on the tour.

The process consisted of an assessment and then an online interview. They conduct an in-person interview for the final round with a two people, during which you also tour the plant.
