I mean, I'm guessing this is the main reason that they passed on me, but I'll never know for sure. Maybe they didn't like my personality. Maybe it was some other question I thought I did well on but didn't even realize I got wrong. Maybe a combination of things.

For what it's worth, I didn't get a very good vibe from them. The impression I got was that their culture was more aggressive and competitive than I like. (Maybe this was to be expected for a company that made a competitive eSports game.) I'm not really what you'd call a brogrammer.

So it was probably for the best that they said no. I ended up at Google, which has been better for me in every possible way.
