It's a video interview. The interviewer asked several basic CS questions first, then he asked some behavior questions. Finally he asked me to solve a coding problem to see the coding skills.

Some basic knowledge about C++, what's the difference between pointers: smart pointer and weak pointer how to implement some standard data structures. What is polymorphism, what is publisher-subscriber pattern, what is factory pattern..

The interviewers are nice, they are professional and patient. They will lead you to find what you are good at. And you can know whether you match the team after the whole process.
