Tons of C++ trivia, mainly about OOP and stuff. Nothing really past though, not much of OOP design patterns, more of just how OOP works in C++ like keywords like virtual and stuff.

Heavily focused on technical aspects with OOP and multi-thread knowledge based on C++. Started with 2-3 minute of self-introduction, then asked some C++ core knowledge and finally 2 coding questions on implementing multithread in c++. Fairly difficult for junior position.
