I applied online. The process took 3 weeks. I interviewed at Arista Networks (Santa Clara, CA)
Interview
An hour-long phone screen dealing with C related questions and hopefully, one coding question. Second round was F2F with an engineer/manager. I don't know of any other company which emphasizes on C so much. You should always look for generalists who are smart enough to write working code. Getting into the internal details of C is the old-school way of taking interviews. It just checks your knowledge (considering that all your questions are posted online) and I can see how the engineers over there are selected. Yuck. Left a sour taste. So not what I was looking for in a potential future employer.
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.
