    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.

    Software Engineer Interview

    Anonymous Interview Candidate in San Mateo, CA
    Anonymous Interview Candidate in San Mateo, CA
    Application Details

    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.

    Senior Software Engineer Interview

    Anonymous Interview Candidate in San Mateo, CA
    Application Details

    I applied online. The process took a dayinterviewed at Roblox in June 2011.

    Interview Details

    After a chit-chat type of phone interview with an onsite recruiter, I was asked to come for an onsite interview.

    One VP, one senior member and one DB guy.

    The VP asked some general architectural system design question, which could have vastly different right answers depending on the nature of the system.

    The senior person asked a question about finding certain set of numbers from a list, I gave an answer with O(N), but he insisted that sorting the list gives a faster solution. There is no sorting that can give performance faster than O(N). I was tempted to correct him, but I just kept quiet.

    The DB person asked didn't ask any tough question. Probably because he knew that I was not a DB guy.

    Overall, I felt that the people seemd sub-par in their engineering skills/creativity.

    Interview Questions
