I applied through an employee referral. The process took 2 weeks. I interviewed at Arista Networks in Dec 2023
Interview
The first round was decently easy and the interviewer was really nice and helpful. One was a LinkedList question on deleting certain nodes. The other was on binary operations. He gave two functions and asked about what each function was doing and which one would be faster (they were both counting number of 1s in a number but in different ways).
The second interview was pretty difficult for me. The interviewer started off by asking what my favourite language is (python) then asked me the difference between languages like python/java/c and how I would explain it to a highschool student/college student etc. for half an hour. Then we went on to coderpad and he ask how to solve sudoku. Wasn't able to solve it in half an hour unfortunately.

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
