4 rounds - 3 Techincal + 1 Managerial. Appeared for the Azure compute team hiring. Technical rounds included system design and some basic DS & algo. Managerial round was more of another technical round where the manager was trying to show off his knowledge in OS. It looked like he was interviewing for some kernel developer which was nothing related to my work experience. The guy seemed least interested and was yawning and coughing throughout the interview process. Some lame questions were asked which was mostly related to the work his team does, any outsider without enough domain knowledge would find it difficult to comprehend any of it in 10 mins and come up with the design for it which otherwise must have been built by a team working over a period of time. Kept asking things from C/C++ which was not even my skill set. Overall a very bad experience, expect the manager to just spend some time over the candidate profile to look for basic match before calling for interviews, it was a such waste of time.
