Interview
First process was a pretty easy string manipulation question on HackerRank, after solving that, There was another technical interview with a great interviewer, which I’ve just left 10 minutes ago. It’s safe to say the interview was one of the best interview experiences I’ve ever head. Interviewer did not just wait for me to solve the question, he walked through the problem with me and simulated a “pair programming” environment. He was kind and communication was on point. Even if I dont’t get to see the future process, this was a great experience! Kudos to Arista.

Some simple checking operation on a string (const char*) with C

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

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.

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!
