I applied through college or university. The process took 2 weeks. I interviewed at Arista Networks (Calcutta) in Sep 2014
Interview
the first round was online aptitude round. Then we had technical interview round and final a HR round.The online aptitude round consisted of some basics of computers, aptitude and logic reasoning and verbal reasoning. Technical interview they were asking questions from C/C++, java, DBMS an the projects. finally we had HR in which we were asked about our interests, what we want to do for our future, our family background, why do we want to work for this company, why do they select us and many general HR questions.
Interview questions [1]
Question 1
In the technical interview round they mostly focused on the project which I did during my summer internship and I was also asked few puzzles.
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
