First round had a very brief component asking about my prior work experience and then 2 technical questions, one was regarding prime factorization and the second was regarding expectation of a certain stochastic process. The interviewer gave hints in moments where I was stuck. It seemed that I needed to solve the problems without any hints in the first round in order to proceed to the next one.
