I applied through a recruiter. The process took 2 weeks. I interviewed at Arista Networks in Feb 2019
Interview
Was contacted by a recruiter on LinkedIn. The first interview was a technical interview, solved two problems, one in python and other in C. The questions were exactly the same as mentioned here, missing number and other was a long one.
The purpose of missing number was to see you can code and long one was to assess my knowledge of C, OS and cache (pretty much all I know about something).
Cleared this interview and was offered final 2 technical interviews. Had to pass first to get second interview and they were back-to-back.
I couldn't get through the first interview, the question was to assess my knowledge of assembly. The most difficult part to realize that problem needs to be solved in assembly. For the reason interview talk in manner of how would you change the compiler. The question was regarding how printf worked with variable parameters.

Question 1
How printf works, regarding stack pointers (assembly)

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
