I applied through other source. The process took 1 day. I interviewed at Arista Networks (Dublin, Dublin) in Jan 2017
Interview
Coding challenges over SSH. Very proactive in contacting me, seemed very competent. I wasn't very surprised to be rejected as I wasn't that well qualified. I used the Vim text editor which I am very used to but I think this was expected. I did all of the problems but made a few mistakes - though I fixed all of these in the end.
Interview questions [1]
Question 1
Reverse as string, Delete duplicate node. A few more along those lines. All in C.
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.
