I applied through college or university. The process took 2 weeks. I interviewed at Arista Networks (Nashua, NH) in Oct 2015
Interview
I met Arista at the college job fair. One phone interview with coding was all that was required. I was asked basic C questions regarding structures and performance times and algorithms to figure out a binary search problem. Nothing was too hard, but you need to know your C. The interviewer is very friendly and willing to guide you with hints.
Interview questions [1]
Question 1
They ask you to ssh into their recruiting server and read/write/compile code in C. Will respect the NDA
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
