First video interview trough HireView. Then a face-to-face interview with HR manager. At the beginning of that interview, they made me sit a 15 - 20 min physics/mechanics competency test (pretty easy for anyone with a mechanical engineering background). The questions are quite typical at this stage, mainly checking your skills, motivations and understanding of the job. They also ask for a role-play where you pretend to try to sell something to the interviewer. Its ok if you don't sell it to them, just remember to apply to SPIN sales method and be engaging) Then a face-to-face interview with Managing Director. Pretty laid back; can ask you for role-play again. General questions about your motivations etc.

My interview process consisted of two rounds. Was flown out to Chicago to role play one of their products. Thirty minutes of behavioral was pretty typical. The thirty minutes of technical role play was on the more difficult side - thought it went well but wasn't given an offer.
