Took a few weeks to get a resume response and then another week to get the interview. The technical interviewer only asked two questions. One Android related but it was very random and the other some very random financial algorithmic problem. No live coding. Nothing you can study/prepare for. I am not sure how you can evaluate developers based on only two random questions that nobody else asks in interviews. CTO asked some behavioral questions. It was hard to understand what answers the technical interviewer was looking for at the time as there many ways you can do it so I got rejected. Plus I had a bad headache at the time and could not think straight. The financial algorithm requires some thinking so it is not a good choice for on-the-spot speaking question.
