It was 3 back-to-back interviews with the engineering leads from each team on engineering fundamentals, followed by 2-3 questions about your projects. They are extremely kind and will help you to the answer if need be and its a very friendly environment.

1 on 1 interview. It started out with talking about Experiences and my resume but then they started the technical questions. They asked 30 technical questions from heat transfer, fluids, circuits, and strength of material. This would have been a lot easier if I was aware of the technical questions before the interview.
