Very nice interview. Started with very basic concepts of C++ like main function and its arguments. Covered OOPS concepts, static and dynamic casting. Interviewer allowed to look into documentation when in doubt.

First part was an interview with a manager who asked me a few technical questions, 90% of them completely unrelated to what I do. It seemed that he just followed a script made by someone else, since some correct answers I gave was not friendly accepted. He interrupted me multiple times while I was explaining why I would do certain things. To my surprise, they wanted to proceed to the second round. This time it was with two engineers, who presented a technical challenge, another conceptual one, and another about general micro services communication. One of them was kinda friendly, while the other was kinda distant, cold.
