Initial interview was with hiring manager and lasted around 30 mins. No technical questions. I was asked to tell about myself and my background, and to describe the job from my perspective. On the very same day I was invited for a full-day of in-person interviews at their headquarters, which took place a week later. The in-person visit to their headquarters was intensive, as it all lasted from ~10AM - 5PM, and included scientific presentation about a publication featuring their instrument, and back-to-back interviews with different people from the team. One of the interviews was technical while the rest were discussions and behavioral/situational questions, related to different scenarios with customers. Final decision was made immediately next week.
The whole process was unusually fast ( ~20 days between my application and final decision). They seemed transparent and they really cared that I have a good understanding of what the job entitles.
