Earlier quoted context omitted.
"There's no effort to quantify what "technical" or "communication" skills are - these are left to the interpretation of a the interviewer." And yet, these scores are measuring something and averaged across tens of thousands of technical interviews, you have enough statistical power to average out the particularities of each interviewer. I'm sorry you find the results repugnant, but the results are what they are. And…
It's not the results I find repugnant, it's the assumption that the results have any real world validity. The _something_ they're measuring is as likely to be demographic biases as it is technical or communication skills.
Of course it has real world validity. It has real world validity regarding how well people are likely to do in tech interviews.
You can feel free to say that the way the tech industry does interviews is bad, or biased, or has all sorts of problems. But having vague measurements, such as "technical" or "communication" skills sounds very accurate to how tech interviews are actually done, in the real world.
All the moral outrage everyone is having about this, seems to have nothing to do with the accuracy of the report, which is about measuring tech interview performance. And it instead seems to be regarding the tech interview process in the industry, in general.
