The interesting thing is that Google found that behavioral interviews better predict employee performance. I'm not sure why they didn't change their interviews after that internal study..
Because the people giving the interviewers were hired under the old system. Which they can't just turn on its head, all of the sudden, because that would... invalidate the exacting, methodical "high bar" which they had to pass in order to be hired (though proving their Great Developer status).
That is how they hire business majors, not engineers. High end business major job interviews usually has a ton of questions like "why are manhole covers round?", and google realized that such questions where worthless.
The technical interviews are totally different and are used because they actually work well, but you can't do something similar with business skills.
No, but there are many other places where they talk specifically about non-tech roles and I have never seen him comment on technical interviews. Example of article talking about non-tech roles:
