There were two interviews. First interview had algorithm coding questions. Second interview had machine learning questions and it again there was algorithm coding questions. The interviewers were supportive and helpful.
I had one phone interview focused on ml breadth. Then a 5 hour onsite interview Focused on machine learning breadth, depth, application, coding, and mostly on leadership skills and principles
