I had five interviews overall. Two for coding, two for research (ML in my case) and one for HR interview. The coding interviews were not as hard as the ones SWE are having, which made a lot of sense to me. All of the questions were taken from different preparation sites (I saw most of the questions for the first time during the interview but I was able to locate them to see if I got those right). The ML interviews both were about designing an ML pipeline from understanding what is the basic need of this pipeline up to deploying it.

7 Interviews, didn't receive an offer after the final round. Time-consuming process, which includes multiple rounds of technical interviews (design, coding, behavior, etc.) and a 1-hour research talk. The team leader was unpleasant to interact with.
