It was a 2 step interview, both with the team manager. On the first one, i took a test with 3 algorithms problems and some basic multi-threading questions. The second one was about relational databases and basic multi-threading problems.

Was asked questions about my previous work(especially that which pertained to C++), then OOP in C++ (but mostly within C++11, no newfangled stuff), then an open-ended discussion. In the end, we wound up talking about my Python experience (they had one such role to fill)
