I'm so tired of this crap where we pretend discrimination isn't discrimination if we jump through a bunch of hoops. Yes asians being told they can't come to interviews because they're too asian is racism and it does impact their chances of seeking employment because how you do on any given interview is going to be to a degree random. You could get a coding test you've never seen before or one you practiced the night before.
The whole song and dance about applying racism at the interview selection stage isn't about not being racist, it's that there isn't court precedent that specifically makes that illegal, but there is for other more direct techniques like racial quotas.
