Software Engineer Interview

Difficult Interview

Application

I applied online. The process took 1 day. I interviewed at Commvault.

Interview

Received an email asking me to take an online test with a webcam watching. The test also spies on the contents of your computer (set up a dummy account). Testing is obviously outsourced to India. Spelling errors, bad grammar in the instructions, plus the test environment is very buggy. You get an hour, and I probably spent a third of that fighting with the test itself. Afterwards I never heard from anyone again. No email or phone call. Very unprofessional company.

    Difficult Interview

    Application

    I applied through college or university. The process took 1 day. I interviewed at Commvault (New York, NY) in October 2016.

    Interview

    First Round of the interview process. Took an online coding test with a group of other interviewers. We all brought out own laptops. The test was 45 minutes, 3 questions. No outside help was allowed and you are monitored at all times. Their coding environment had no syntax aids or autocomplete and because you could not look up language specific functions or syntaxes, the biggest challenge for me was trying to remember how to do specific things in code by memorization, something I have never done. The problems themselves were not difficult, but relying on memorization of coding syntax is necessary and not knowing them costs you dear time, something you do not have a lot of.

    I applied through college or university. The process took 2 weeks. I interviewed at Commvault (San Jose, CA) in February 2015.

    Interview

    It was an online test with webcam and desktop sharing. It consisted of 5 programming questions, where I was asked to code certain methods for the problem described. I took a test in Java as the position was for a java developer. It was fully based on Java concepts like generic class, exceptions, multi-threading, linked list, arrays. All it needed was the thorough knowledge of java concepts and ability to understand the problem statement clearly in a short span.

    I applied through college or university. The process took 1 day. I interviewed at Commvault (New York, NY) in February 2014.

    Interview

    It was the first technical interview, and I and bunch of people had to solve some programming questions in a big room. We had 90 minutes to solve 3 algorithm questions. The questions are not that easy or not that hard. But you can use internet freely during the test.

    Interview Questions

    • The questions were related to data structure problems such as linked list, tree, etc. You code in a web browser, and it's tricky. It is basically just like using a memo pad.   Answer Question

    I applied through college or university. The process took 2 weeks. I interviewed at Commvault (Gainesville, FL) in October 2013.

    Interview

    Commvault had visited our campus for the career fair. Some of us got a mail the same night to attend a programming challenge the next day at the University.
    There were three programs with 5,6,7 marks. They instructed us to solve any one first and then attempt the others.
    Question were : Convert a number to binary, Find if a loop exists in a Linked List. Can't recall the third one.
    It was a online compiler type interview. So you had to write, compile execute and pass their tests.

    I then got a mail for a telephonic. The guy asked me just one question.
    char *a="something";
    Is this valid or invalid. Give reasons.
    Then what would
    strlen(a) return?

    The next question was what is sizeof.

    That's it. Simple basic stuff.

    • char *a="something"; Valid / Invalid.   1 Answer
