I applied online. The process took 4 weeks. I interviewed at Arista Networks in Aug 2023
Interview
First an easy HackerRank coding test. Then two stages of live coding tests which are 1.5 and 2 hours long respectively. You'll have to SSH their server and code in a command-line text editor of your choice (vi, emacs, nano etc.). All interviewers were very friendly and helpful. Unfortunately I got rejected after second stage.
Interview questions [1]
Question 1
1st stage:
- Implement strcmp in C/C++
- Find the Missing Number in a sorted array
2nd stage:
- Sieve of Eratosthenes
- Longest Common Subsequence
- Inorder Traversal: Required Data Structure + Next Node Fn
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
