There were three rounds in total, with the last two rounds taking place on the same day.

I was first contacted by a recruiter, who provided detailed information regarding Arista Networks and the interview process. I answered some questions via email and attached my transcript.

The first round was a 45-minute phone interview.

The second and third rounds were two hours in total, with each round lasting one hour, also conducted via phone.

A verbal offer was extended at the end of the third round.

First round: Memory management in C/C++. Some coding questions, similar to those found on LeetCode, to be coded in C.

Second + third round: API design. Detailed questions about the performance of the design. Write implementation (compilation not required). GDB debugging. Some C programming questions related to pointers and functions.
