    Difficult Interview

    Application

    I applied through college or university. The process took 3 weeks. I interviewed at Arista Networks (Los Angeles, CA) in February 2017.

    Interview

    Met a representative at a career fair, and it went well when I told him about my interest/experience in dealing with networks. As we were talking he put a star on my resume, which led to being invited for an interview. All the interview questions he can ask are already posted on Glassdoor, so make sure to check all of them out. The interviewer only expects that you spend all 45 minutes on one question (vercmp), but if you practice, you can answer more (I fully coded/answered 3 within that time). However my vercmp wasn't able to work in time, so that's probably why I didn't get the offer.

    Interview Questions

    • 1. Vercmp in C using strtok.
      2. Find the missing number in a sorted array of numbers. Binary search, O(log n) time.
      3. Given a linked list and a target value, delete all nodes with that target value in the list.
      4. Look at and understand 2 bit manipulation functions, which one is faster, use gettimeofday to time the functions.

    Average Interview

    Application

    I applied through college or university. I interviewed at Arista Networks in February 2017.

    Interview

    Phone Interview. The interviewer was very nice and patient. Like everyone else, I was asked to login their server via ssh and finish some coding problems. In addition to the problems themselves, I was also asked some questions about the C language and computer systems.

    Interview Questions

    • The problems are almost the same as what others have posted here, but to answer them well, you'll have to be very familiar with C (yes, C not C++), command-line debugging, man page, and working with editors like Vim or Emacs.   Answer Question

    Easy Interview

    Application

    I applied through college or university. The process took 1 day. I interviewed at Arista Networks (Atlanta, GA) in January 2017.

    Interview

    It was my first interview and it was great. The interviewer was nice and it was a easy interview but I wasn't prepared enough on some fundamentals in operating systems, actually computer systems stuffs. The algorithm part was easy and it's better to use C or C++, otherwise prepared for tricky questions for Java or other languages.
