First screening part, telephone call.

As I was fresh out of university, I was asked some basic questions about C++ language and computer science.

Classes, templates, inheritance, polymorphism.

Then, I was asked for an interview at the facility.

I was asked a bunch of questions about data structures and a few about algorithms. Part of the interview was done in English; the rest in Polish.

Generally speaking, it was a nice interview.

They wanted me to implement a stack and asked me details about C++ language, such as class implementation, templates, C++11 and C++14 features, virtual destructors, etc., and general CS knowledge, like big endian and little endian.

Also, they asked a few questions about algorithms and data structures, including trees, lists, vectors, arrays, Dijkstra's, and Johnson's algorithms, etc.
