There were a 90 minuets online test, that consists of 2 problem solving questions and 4 MCQ questions. After that, I had 2 on-site interviews. The first interviewer failed to break the ice, and seemed to be inexperienced enough, she asked a classical problem solving question, but stayed silent through the whole problem, and hardly confirmed the solution when I finished. After that, she asked a lot of machine learning related questions. The second interviewer was very nice, helpful, and friendly. He asked 2 very good, fairly-hard problem solving questions.
