I applied through an employee referral. The process took 1 week. I interviewed at Arista Networks (Santa Clara, CA) in Aug 2011
Interview
There was a one hour phone interview which was very rigidly structured and I was asked to write code in a shared terminal. The phone interview can be aced by anyone who has some recent experience in coding typical programming interview questions that are asked by every software company.
Followed by the phone interview, there were 2 in-person interview sessions ( 1 hour each ). This meant I didn't have to take a full day off at work, which is great. The in-person interviews were a little more open ended and again, it was very typical of software company interview questions. The interviewers do not ask anything from the resume and dive direct into programming questions.

Question 1
Write code to find in-order successor in a binary tree.
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
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
Application
I interviewed at Arista Networks (Vancouver, BC)
Interview
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!
