The interviewers are super nice. They asked a lot of machine learning questions and would focus on what techniques you know on your resume. It is not only about what you did, but about the process, the technique, and your understanding of what you do. Even if you made a mistake or say something ambiguously, the interviewer would lead you to the right path. Overall, very nice interview experience. The first round is technical + behavioral, the second round is a coding project to build model according to what they provide you, the third round is to meet several managers to chat about technical.
