It can be something as simple as being in a team of gamers, and not being a gamer yourself. You are naturally going to stick out, and not have as good a time as if you are in a team of people who like cycling, or have families like you do.

Age can be a difference, not obvious as being treated differently, but just having different humuour levels, or doing different things on the weekend can make it harder to bond.

I can see not being a gamer or not liking beer making anyone a social misfit, regardless of race. I'm a white non-gamer and I've uncomfortably sat through so many gaming conversations. They just go on and on and on.

It's true. And for as much flak as "cultural fit" takes in the popular press, everyone's going to be happier if people get along. Look hard at this stuff when you're thinking about joining a company, you'll spend a lot of time there.
