      Application

      I applied through university. I interviewed at Arista Networks (Jammu, Jammu and Kashmir) in Sep 2019

      Interview

      The interview process started with an online coding round containing 3 coding questions which were not so straight forward and required good knowledge of C/C++ and data structures like linked lists, tree, stacks, etc. Then, there were 3 rounds of interviews. The first round focussed on basic knowledge of data structures and the questions were pretty straight forward initially but then some portion was also concerned with system design. Also, in the 2nd round, questions were based on Operating Systems and System Design. The 3rd round was HR + System Design round.
