I applied through college or university and the process took a day - interviewed 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.
Interview Question – For a hundred round of round-papper-scissor and connect 4, which would be more interesting. View Answer

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.

Very Difficult Interview
I applied online and the process took a day - interviewed 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.
Interview Question – Some question about storage (could not understand due to think accent)... View Answer
