I applied through a recruiter. I interviewed at Arista Networks in Jun 2026
Difficult interview
Application
I applied through other source. I interviewed at Arista Networks
Interview
The first round was an online coding test conducted through the HackerRank Portal. It was a single question with 60 minute time limit. Round 2 was in their offices, again a technical coding interview and some questions about C/vim/gdb. Round 3 was two separate 1 hour technical interviews, again with a variety of coding questions about Binary trees, virtual memory implementation, word puzzle games.
Interview questions [1]
Question 1
Solve a puzzle game where words in a diction needed to be found in a grid of letters, implement this in C.
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
