Very standard. First a programming test on hackerrank, then two algorithmic interviews, then a C++ knowledge interview with a team lead. It turned out they were looking for candidates proficient in C++.

technical questions on computer science basics, shouldn't be too hard for people with technical background. One question on harsh map internal implementation and one question on parallization. The interviewer is really nice and did't give me a harsh time although i didn't come from an engineering background.
