I applied online. I interviewed at Arista Networks (Bengaluru) in Mar 2018
Interview
Applied through LinkedIn, got call from the recruiter. The first thing they ask is your current package, be careful here their entire offer will be anchored around this value.
They asked to come for interview the next day.
Round 1
2 questions on the Hackerrank, simple string and prefix tree data structures.
Round 2
A program written in C, expectation to debug with gdb and the complete the second half. Again straight forward.
Round 3
Design questions with the a senior developer/manager.
Round 4
HR based discussion with another senior manager.
Few things about Arista
1. They have peer review based rating system, which determines your pay grade and other stuff.
2. They are known to give large bonuses at year end and their stock increased a lot in mid 2017-2018 but is largely stable after that.
3. There was no room for negotiation after their offer.
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!
