This was a technical round based on data structures, networking, operating systems, and project work.
My interviewer was very polite. He asked me to introduce myself and then he introduced himself.
He asked me about my projects. I explained two of my projects to him. One was related to customizing Apache Web Server, and the other was based on LSB Technique of Image Steganography.
There were some cross-questions. He wanted to know the motivation behind the topic, as well as the tech stack I used to implement the projects.
After that, he asked me a lot of questions surrounding OOPS concepts, DBMS, OS, and Networking.
Explain the layers of the OSI Model.
Abstraction vs Data Hiding
CPU Scheduling techniques and some conceptual questions regarding that. After that, he asked me to implement encapsulation.
After this, they asked me about my preferred programming language. I said C++, so there were a lot of questions regarding that, like how doubly linked list is implemented in C++, Interfaces, Friend functions, and some more
