Only got the first round interview. First explained a professional or academic project. Then, did a lot of math and programming questions, not very difficult. The math questions were mostly probability questions and the programming questions were some conceptual questions.

Terrible. Phone screen interviewer had an accent that sounded nothing like English, had to ask him 3-4 times to repeat questions, still couldn't understand him. Nothing about my resume, leadership, or qualifications, nothing behavioral. Just asked me math questions, and when I explained my answer he rudely cut me off and went to the next question. Not happy with the process at all.
