Here are the most commonly searched roles for interview reports -
Recruiter reached out to me on linkedin. She was friendly and professional. She mentioned the interviewers were picky. I scheduled my technical screening for 3 weeks later.
The screening went well. Asked about my resume and two coding questions in C.
The final interviews were 2 back-to-back. The recruiter said they could reject after one, both or give an offer on the spot. The first interview went well. Purely technical depth questions. The interviewer left to talk to and bring in the final interviewer.
The final interview was with both interviewers. More technical questions. I had no opportunity to ask any questions myself. Then they said they would deliberate for 15 minutes.
After 15 minutes they came back to ask me yet another technical question. At this point the interview is 30 minutes past the scheduled time. They then left to deliberate again.
They come back and say I’m not a good fit for the position.
Other Software Engineer Interview Reviews for Arista Networks
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!
