Two telephonic rounds. Four onsite rounds + one lunch interview. Leetcode algorithm and data structure based questions. C++ mandatory in all interviews. Some brief discussion/questions on computer vision and machine learning/deep learning.

There were three phone screening interviews for the background check, simple probability question, and simple coding problem (not the algorithm one). And they invited me to the office, there were several 1-on-1 interviews about 5 hours. All the interviewers asked me some questions about coding/geometry.
