Second—this strikes me as fairly standard cultural shock. It's one thing to find yourself immersed in a culture, it's quite another to find that you have to immerse yourself in that culture to reach your teammates. This is an experience I have not encountered before; people have surprised me with the lengths they go to ensure a healthy diversity in company culture so that everyone feels like they have an opening to communicate. Why would you NOT want to get to know your teammate? If they have different interests, it's an opportunity, not a problem.
That said.... sometimes you need to be the person to push for the cultural diversity, and unfortunately, that's not going to be easy for most people regardless of sex or industry. I would even imagine non-tech companies actually have a much worse case of this where EVERYONE feels alienated from their coworkers based on my personal experiences.
It's complicated. But monocultures are certainly terrible teamwork oriented groups of people—I think we can all agree with that.
