I applied through university. The process took 4 days. I interviewed at Arista Networks
Interview
The first step was an online test consisting of a set of mcq questions followed by coding round containing 2 questions to be solved. This was followed by 2 sets of interview rounds. One was mainly focussed on coding where i was asked to do a relative simple linked list question from scratch on my local code editor with screen sharing enabled. I was expected to do speak my reasoning as i typed each line of code and then run. He asked few questions related to hashing theory as well. The second interview was based on my resume where the interviewer asked my topics related to the electircal domain project that i had put.
Interview questions [1]
Question 1
What are the methods to avoid collisions during hashing
I applied through university. I interviewed at Arista Networks (Burnaby, BC) in Feb 2026
Interview
2 questions using C, one about debugging a program, one leetcode easy question. Debugging question was quite low level (about memory alignment etc), leetcode was a linked list. Asked about resume projects/experiences too.
I applied online. I interviewed at Arista Networks (Dublin, Dublin) in Nov 2025
Interview
First round was a Hackerrank coding problem set that consisted of solving one problem to do with string manipulation. The problem was timed (42 min time limit) and the solution was reviewed by someone at Arista Networks.
Interview questions [1]
Question 1
How would you take a string containing random characters and manipulate it so that you output the string in blocks of 3 with only alphanumeric characters in it.
Interview started with a few questions about your resume/background and then went into technical questions from these fields. Majority of the interview was a coding technical with a find the bug problem and a leetcode medium.
