Was it a proper double-blind study substituting interview result for rnd() to make a hiring decision? And established correlation a few years down the line? Because what you've stated: 'data shows' ... "successfully pass go on to be successful" - sounds like cargo cult science or pseudoscience to me.

Google generally isn't known for pseudoscience.

  You've stated 'data shows'. So my question was - was it a proper double blind study? Because it is definitely possible to do it properly. Substitute the results (or partial results) of the interview with rnd(), use it for hiring decision for a subset of candidates. Keep this information confidential. Establish if parts of your interview process don't perform better than randomness a few years down the line. It's possible to do. Only I don't think this was done. And if it was not done, and the method was some 'data shows' with hand-waving - it would be under definition of pseudoscience.

    You're calling most scientific journals psuedoscience -- even the hard sciences, like astrophysics. Nobody's doing controlled studies of supernovas, they're drawing inferences from observational data. I don't think your definition of science is sustainable.

  Even Google has a PR department dumbing things down.

Do you really need to do the double-blind study, though? The median person cannot program at all, so using rnd() couldn't possibly have better than a 50% success rate (certainly lower; 50% is just a round number that I'm sure is larger than the number of programmers). Is Google doing worse than that? I kinda doubt it.

  Yes. You can do it at each stage as well. And we are not talking about hiring a general employee but a CS or programmer. So employ rnd() after a resume screen. Google has already found that GPA and brain teasers had no positive effect. This is similar and it would be an interesting experiment.
