One call with a recruiter, 3 calls with engineers, then an in-person interview. Things were organized quickly and I heard back within a couple days of each interview (aside from the in-person which took a few weeks to hear back).
Interview questions [1]
Question 1
What is the most technically challenging thing you have worked on, and can you walk me through your thought process?
4 rounds, 1 with technical recruiter, 1 with engineer, 1 with manager, and onsite. first 3 are over the phone. onsite was the challenge, consists of presentation, one-on-ones, and tour.
Rigorous but fairly reasonable in my experience. The technical problems often has a twist but if you have strong fundamentals you should be able to perform well. The recruiter and interviewers I interacted with are all very nice people.
30 min call on personal projects and technical questions with recruiter. Technical questions were relatively simple and focused on engineering fundamentals, about cantilever beam, incompressible/compressible flow, and ideal gas questions.
