Because they are interested in it. Just like some like math, others like sports.

Why e.g. women are the majority of teachers (at least in my country)? They like to teach, are good with children.

That's natural and you won't change that with ads that reverse the ethnic proportions in given country.

Also, depending what on the source white people (in the US) account for between 60 to 70 percent of the tech work force.

So I'm genuinely curious why PoC might get problems with getting interviews? Do US based employees biased in some way, still in 2021?

All that matters for me in interview if is that person smart enough and nice enough to work with.

I don't see a lot of black people in IT, but I see plenty of Indians and Asians - those are also PoC I assume.

But if your parents are good at math, chances are high that you will also. Genetics play huge role here, for some learning e.g. math is harder than for others.

Amazing that people went from "we need all colors represented in ads as best as possible" which was completely reasonable, to "maybe we don't need white people in ads at all sometimes, ok? maybe it's a good thing!" which is objectively an absurd stance.

I don't get how some occasional over representation of minorities bothers people this much.

It wouldn't bother me a bit if it happened in my country.

It bothers a bit because it such an obvious thing, where they had to go through and find the exact people they wanted and you know that they purposely did it because it's "the thing" right now.

Then in this case I say: "why is this not representative of the people of this country!?"

Your response, a smarmy "why not?" and personal attack.

The failure can speak for itself.
