I applied online. I interviewed at Arista Networks (Bengaluru) in June 2017
Interview
It was a standard interview process of 3 technical rounds, each being an elimination round. Pointers, Linked Lists, and Linux system Calls were stressed upon. Read all the previously asked questions on glassdoor. Operating System basics are also asked.
Interview questions [1]
Question 1
1. Simple question involving char* passing to another function where it is changed. Asked about output.
2. A program printing an address of a variable. Will the same address be printed if run multiple times? What if 2 instances running at the same time using forks. What address is returned when the address is printed, virtual memory address or physical memory address?
3. Linked list question to remove two adjacent nodes if their sum equals some given value.
4. What system calls are called in Linux when any command is given to the terminal.
5. Question involving struct hack, structure padding, and incrementing a pointer initialized to NULL.
I applied through a recruiter. I interviewed at Arista Networks in June 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
