      No offer

      Application

      I interviewed at Arista Networks

      Interview

      First round, one hour on site coding test. Removing multiple elements from a linked list. Then questions were asked on networking, data structires. Second round, 2 one hour interviews. The first hour is very technical, was told up front that there will not ne a second round if things don't go well. Implement a stack API in c, several topics were touched upon. The second round, the interviewer seemed to have preconceived notions of what answers to expect. If the answers deviated even slightly, they were not accepted. Looking for concepts like internals of printf and variable argument functions.

      Interview

      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!
