    Interview Details

    Entire process was great, had a few phone screenings, and onsite as well. People were very friendly, knowledgeable, and cool. Great company overall, and smooth process. Took a couple of weeks total. Interview questions were standard, nothing surprising, I wish it was not my first interview, for I would have aced it otherwise.

    Application Details

    I applied through college or university. The process took a dayinterviewed at Roblox.

    Interview Details

    Met at career fair and was contacted a month later. The recruiter was very helpful in setting up the phone interview with their manager. But the manager failed twice to call at the predetermined time. In the end we talked over the phone while he was driving back home, very unprofessional, and was not fully attentive.
    I would advise you prepare in advance for this kind of situation.

    Application Details

    I applied through a recruiter – interviewed at Roblox in November 2013.

    Interview Details

    Had two phone interviews, one with recruiter and one with manager. Went well. Came on-site and talked to a handful of people for 4-5 hours.

    Overall, it went okay but I was not as prepared for it as I would have liked. They will expect you to be sharp on your programming.

    I applied online. The process took a dayinterviewed at Roblox in January 2012.

    Interview Details

    I received a call from a Russian chap with a heavy accent. I am a native English speaker and typically have no problems understanding accents. I've been in the Silicon Valley for years to no big deal. In this case -- it was a big deal. I could barely understand the chap interviewing me. It made me very slow to reply and I had no idea if I was answering what he was asking.

    Now I am a C++ guru. I have knocked it out of the part in interview after interview in this area. This guy asked one question. I did not fully understand it. The answer ultimately required you to know to use an STL hashed-map. I was just rolling my eyes wondering "how doe these people hire anyone"?

    One of the oddest interviews ever. One question and a guy I could not understand. 15 minutes tops. I already had other offers so I was already pretty turned off by Roblox.

    I put Very Difficult b/c I could not understand the guy.

    The process took 4 weeksinterviewed at Roblox in November 2011.

    Interview Details

    The recruiter somehow got my resume and approached me. The company is on the edge of spanning so it is looking for a bunch of new positions. I showed the interest on doing backend server side programming. As a result, I was arranged for a first on-site interview with the technical director. However, this interview is just a chat about my background, some general issues on the backend design. Then after two weeks, I was arranged another round of on-site interview with 4 people. The interviews did not contain too many algorithm or programming puzzles, but really some advance questions that fit their needs.
