In 2021, 9% of computer science graduates were black (1). 18% were women (2). These numbers are the ceiling of what you might expect for a senior pipeline, since women attrit at a higher rate than men (3).
In a typical senior hiring pipeline for a Microsoft-scale company, while you'll have loads of applicants, you might have a dozen who make it through initial screening and are at least qualified on paper. I've been a hiring manager at companies slightly larger, and slightly smaller, than MS, and this was true at both.
So of those 12, you'd expect perhaps 1 to be black, and perhaps 2 to be women - optimistically. But every company, but especially high-profile fortune 100s, are trying to increase their D&I numbers. Qualified minority candidates rarely come through applications - instead, they're recruited, since everyone wants to somehow turn that 18% into 30% in order to get their D&I-linked bonus.
Blaming a hiring manager or company for their "pipeline" when they fail to hit impossible targets is absurd, and mathematically dishonest.
