7 rounds of interviews. One presentation, three research design, one coding, one ML basics, one behavior. Coding is basically leetcode coding questions and ML basics are just like review basic machine learning concepts such as metrics, PCA, kmeans, knn etc.

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.
