Applied via the Arista Networks career portal. I received a call immediately.

The first round was a phone interview where I was asked to SSH to their server, write, compile, and pass test cases for three data structure and algorithm-related questions in C. I passed all test cases for all questions and was selected for the second round.

In the second round, I was asked a design question, and in the third round, I was asked about C code snippets and to explain them in detail.

Will respect the NDA. Be solid in C. Operating systems knowledge was beneficial. No networking questions were asked. Knowledge related to x86 stack frames, function arguments, and compilers helped me a lot.
