I applied online. The process took 1 day. I interviewed at Arista Networks (Santa Clara, CA) in Jun 2014
Interview
I sent my resume to them by email. Several days later I was asked to fill the information they required online. After that I get a phone call from the HR recruiter, who discussed something with me then told me that she will sent me a email for online testing. I got the email and completed the online testing and several days later was invited for a on site interview. 2 engineers interviewed. One of them is very kind but the other is not.
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.
