I applied through college or university. The process took 2 weeks. I interviewed at Arista Networks in Nov 2018
Interview
First, they will send an e-mail to you to book time for phone interview, also you could go onsite. For my phone interview, all questions are based on C programming, they will need you to ssh to their server and all questions are there.
Interview questions [1]
Question 1
Find missing numbers in a sorted array, like [1,2,3,4,6,7,8] you should output 5, all integers, consecutive and non-negative.
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.
