I applied through an employee referral. I interviewed at Arista Networks (Vancouver, BC) in Dec 2023
Interview
The first round was of medium difficulty level : basically linked list and array was asked . Interviewer gave 2 coding questions on coderpad.
Second round they asked me to create API's, Create a data structure, I Created but he added more and more things to confuse me, and then he started laughing and was behaving very rude . He was not ready to listen your explanation or algorithm he wanted the answer that was already established in his mind.
Python decorators was also asked

I applied through a recruiter. I interviewed at Arista Networks in Jun 2026
Interview
Pros:
Great initial approach – the recruiter thoroughly checked my GitHub profile and projects before the interview, which is very uncommon and shows they do their homework.
Cons:
A major mismatch between the job description ("Software Engineer C++") and the actual interview reality. The technical stage on CoderPad strictly tests bare-metal C98 skills: raw pointers, manual bitwise operations, and packing bytes into 64-bit integers. If you are accustomed to modern C++ (RAII, templates, safe memory management), this will feel like a massive step backward. Additionally, the time expectations for live low-level bit-shifting were unrealistic, to the point where the interviewer started solving the task themselves.
Interview was kind and not stressful, just minor mismatch of naming
Pretty good, not too complicated, was comfortable. Mostly LC questions, and was easy enough that you should be able to do it after doing NC150. good luck for the interview!
Starts with online test, then three rounds of technical interviews follow.
Not a lot of discussion, just go straight to the technical challenges which have to be solved in time
