I've also been "discriminated" against for not being Native American (Casino Morongo in So Cal), and not being an Evangelical Christian (Cal Baptist University).
As it turns out-- those institutions are legally allowed to discriminate. It absolutely blew my mind being asked to "describe my relationship with jesus" in an interview.
There was a technical interview with a very nice guy, who said I scored the highest of any candidate who had ever interviewed for the university.
Then, this sallow cow of a woman with a permanent look of disgust on her face conducted my "religious" interview on subjects like evolution, the Trinity, and my relationship with Jesus.
I tried my best to be "reasonable," but I'm sure I looked like a deer in headlights. It's impossible to be reasonable with unreasonable people such as evangelicals.
My position on spirituality has softened quite a bit as I've gotten older and had a few "spiritual experiences"... but sometimes I wonder if, in the intervening years, if it has occurred to them that beliving in provably false things like creationism, (remember, evangelicals won't even accept that "evolution is gods mechanism of creation"), doesn't make for a good engineer.
Only cause you mentioned "world", its pretty common for only women, or even women who have taken breaks to raise a child to be eligible for many jobs in India, including at companies considered "Big4" like Microsoft.
There is also a suspension of the right to equality in favour of certain castes, and 50-70% of govt jobs and govt college seats can only be occupied by people from these castes.
