      Software Engineer Interview

      20 May 2019
      Anonymous interview candidate
      No offer
      Positive experience
      Difficult interview

      Application

      I applied through a recruiter. The process took 2 weeks. I interviewed at Arista Networks in Feb 2019

      Interview

      Was contacted by a recruiter on LinkedIn. The first interview was a technical interview, solved two problems, one in python and other in C. The questions were exactly the same as mentioned here, missing number and other was a long one. The purpose of missing number was to see you can code and long one was to assess my knowledge of C, OS and cache (pretty much all I know about something). Cleared this interview and was offered final 2 technical interviews. Had to pass first to get second interview and they were back-to-back. I couldn't get through the first interview, the question was to assess my knowledge of assembly. The most difficult part to realize that problem needs to be solved in assembly. For the reason interview talk in manner of how would you change the compiler. The question was regarding how printf worked with variable parameters.

      Question 1

      How printf works, regarding stack pointers (assembly)

      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.
