I applied through an employee referral. The process took 4 weeks. I interviewed at Arista Networks
Interview
Two rounds on the phone screen. ssh to their server to read the question, code and debug. It's better for you to be familiar with c/c++, gcc, gdb. The interviewer is nice. When you are coding, he will give you some suggestion about your coding style. Appreciate with the interview procedure.
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
I interviewed at Arista Networks (Warsaw, Masovia)
Interview
By now I have had only first interview, that was focused on pure DSA. Despite that I would already recommend checking out gdb, cause it came in handy in my case.
