It was a quick process: one telephonic round followed by two technical interviews onsite. The telephonic round involved basic C++ questions, such as polymorphism and virtual functions, and how they are implemented internally.

My interview was quite smooth. I was mostly asked basic network-related questions, which I was comfortable with. Other than that, I was asked about some basic data structures/algorithms and when they would be helpful to increase router performance.

The process was very well planned and simple. I received an on-campus interview call, which was scheduled for three days after the phone call. The interview was mainly about systems and networking.
