      Software Engineer Interview

      Anonymous interview candidate
      No offer
      Negative experience
      Average interview

      Application

      I interviewed at Arista Networks

      Interview

      There were 3 interviews scheduled. 1st interview went very well. In the second interview, the person had muted his mic and even I had solved the question, he didn't say a single word. I had to say myself, "can you check the answer now". He then moved to next question that was inorder tree traversal. Initially I wasn't able to solve it as one check was missing and the function was never going to the right side. He started saying we will not be moving with you, while he was saying, I solved the question but he left the meeting. Asked next person not to take my interview and next person didn't appear at all. Very bad experience, I will ask everyone not to waste their time with this company.

      I interviewed at Arista Networks (Vancouver, BC)

      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!

      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.
