J'ai postulé via la recommandation d'un employé. Le processus a pris 3 semaines. J'ai passé un entretien chez Arista Networks (Dublin, Dublin)
Entretien
The process had three rounds. First I was contacted by recruiter and send link to Hackerrank test. The test had one question about string manipulation and I had one hour to complete it. After that in second round I had to code in C simple functions about more string manipulation. In the third round I had to implement stack and I was rejected on the spot as I had trouble with void* in the implementation in C as I didn't learn it in school. If you are comfortable with pointers and memory manipulation you should have no problem.

J'ai postulé via un recruteur. J'ai passé un entretien chez Arista Networks en juin 2026
Entretien
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
