They started off asking really basic questions. There were 3 rounds of interviews, and it seemed pretty chill. But then, throughout to the latest interviews, they started getting more difficult and hard-hitting.

It was difficult and time was short, so I was not able to finish on time. Better take care of your time before giving the interview. All the best. Go ahead and take the test; it will be useful.

Very long. Four hours of back-to-back interviews in one day. The interview process is with four different teams of two for one hour each. Some of these are systems questions, and some are coding exercises.
