Screening then technical screening then round robin with several different interviewers. Was fairly moderate difficulty questions, nothing special. There was a code review that you were meant to read and tell them what it does. There was some architecture problems.

Did a quick coding exercise where they asked to describe what some code did. Then asked high level questions surrounding how I would build different systems and processes. They asked about how I would approach a high level problem like deprecating use between two devices, setting up a connection between devices, etc. They were all very nice and open to being asked questions themselves.
