J'ai postulé en ligne. Le processus a pris 2 semaines. J'ai passé un entretien chez Arista Networks (Bucarest, ) en mars 2023
Entretien
First part was an online coding challenge. To move forward, have to score 100/100 but the problems were quite easy.
Then there were 3 technical (coding) interviews scheduled with their engineers.
First one was rather simple, confirmed at the end that I will go for the seconds challenge.
Second one was not that hard, but you have to prepare a bit beforehand some classic algorithms and data structures. I didn't move quick enough with solving the proposed challenges and at the end of the session the interviewer told me that I won't be considered for the next sessions and the hiring process there.

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
