Quite technical. Very little chitchat, which is fine. The interview was mostly coding on the big screen, diving into a lot of low-level details. The tone was judgmental and not cooperative. The questions seem to be something you can easily study for, but unfortunately I did not. I believe the interview process does not do a good job selecting the right candidate, only the lucky ones. I would be more interested in how people apply new information, instead of expecting them to know everything off the bat, but none of that apparently mattered at Arista. It was a robotic and cold process. You do the test, they quietly watch you with very occasional involvement, then literally said a couple of words of goodbye. Didn't strike me as a place I wanted to work at anyway (maybe sour grapes, but I think there's some truth).
