The culture thing to me has never meant doing things outside work. Is that a startup thing I'm not aware of? Even in the OP, I don't think that's quite what was meant. It's more a matter of shared interests and compatible personalities.
Maybe you're not the type to hang out outside work, you don't have time, whatever. But how well are we going to get along for the 8 hours a day we spend together?
