in the begining i tell him about project i did , after that they asked me about data tructers i know, after that they asked me questions in oop , polomorphism,inhertence,after that two questions problem solving , in the end i write code in c++ that should implement classes,use of container,pass arguments to functions...

I had one interview with two team members. I had 2 technical questions. The first one was a classic leetcode question. Then they tried to understand if I know the basics of object oriented language and inheritance and polymorphism concepts. After that I was given a question in C++, given a specific class and asked to implement some funcs of this class. It was mainly about graphs concepts and implementations of it.
