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..

There were three rounds of technical interviews including DB, OS, Network, and projects on the resume. My position is about Python programming and web application, and therefore, there were a lot of questions about network and Python.

The interview process has 3 parts. First, they asked some problem about basic CS knowledge, then they looked at my resume and asked some details, finally was an easy coding problem.
