OA then a technical interview asked question involving binary search tree. Medium difficulty. Then asked about some system design questions based on projects in my resume about scaling and deployment.

First interview was the with the HR and then after that round, the next one was an interview with the technical person, and This is followed by two other technical rounds.

There are a total of three rounds of interviews, all of which are technical interviews. The focus is mainly on asking about past project experiences. They will inquire about your thoughts and details. In the last part of the first two rounds, there will be handwritten coding tasks, which are all very simple questions.
