Process
During the interview, I was asked several questions related to the core concepts of C++, computer networking, and operating systems.
The interviewer asked me about subnetting and its implementation on a coding platform, semaphores, and also asked me to code one of the three classical problems: the three-way handshake, virtual memory, or memory closest to the CPU.
It is essential to have a strong understanding of the basic concepts to excel in such interviews. You can steer the conversation, but be prepared for in-depth questions on whatever you explain.
