The whole process was seamless and easy to follow. HR was proactive and very professional from initial discussions, scheduling and follow ups. There was a HR interview regarding this position, followed by a 30 min interview the hiring manager, then another 30 min interview with VP of technology. This process was a great mutual interaction of the technology problems and exchanges. Then, I had a take home architecture challenge exercise to be submitted. This was followed by three more rounds of interview with the Product managers and developers.
