. . . to mention something appropriate to this topic, namely Google, and other tech companies, and their hiring procedures.
We've been reading for years on, on this site and others, about the stringent interview/tests required for Google applicants (and I used to hear the same thing about Micro$oft, etc.), yet nothing brilliant has come out of that company beyond their search engine --- yes, they've purchased the occasional company and added its innovations to their arsenal, but nothing particularly creative has originated in-house.
We saw the same thing at Micro$oft, although having been a contractor off and on there, I can attest to very unmeritocratic and nespotistic hiring going on there, contrary to the publicized bullcrap ---- and no, I've never gotten an interview with them, regardless of the number of work-related bonuses they gave me, and I'm not unique in that regard, yet people of no account have received interviews based upon playing tennis or paddle ball with certain employees, or being related to others.
I see this article/posting as yet another example of what I'm stating.
