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.

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.
