I applied through college or university. The process took 2 days. I interviewed at Arista Networks (Berkeley, CA) in Oct 2018
Interview
First, They ask for transcript and resume. Then schedule phone interview for first round.
After clearing the first round. you get transfer to HR to schedule second round.
Experience wise: I learned so much even though I did not get an offer
Interview questions [1]
Question 1
Round 1:
Build a linkedList
Print a LinkedList
Check if two linkedList are the Same
Last, given a linkedList remove all element that their indices not matching fibonacci number
Round 2:
Memory layout question (stack,heap,static,code) given a code mention where each line goes in the memory.
How to implement stack (what data structure good for that) such as LinkedList or Array
pors and cons of each one of them in term of memory.
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
I applied through a recruiter. I interviewed at Arista Networks (Łódź, Lódz) in Jun 2026
Interview
Reached round 3 out of 4 planned, one was coding task, two live coding sessions. Linux development background was highly expected. Performance optimized approach was tested, specially oriented for hardware with lots of resources. I had a problem to properly understand reqruiting person during round 3, voice was not clear for me.
Interview questions [1]
Question 1
List implementation, bits counting, tre traversal.
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!
