If you mean 50% of the india-based team was female, rather than all of the 50% of the team that were based in india, that shouldn’t be surprising?

I realize my sentence was unclear. My onshore team were all males, all offshore (all India, Bang8, Bang7) QA team members were female.

It's an open secret that multinational companies preferentially hire women in India to pad their global engineering diversity statistics without having to conduct affirmative action in America where it would generate negative press.

An all-female offshore team is pretty extreme though.
