This is BS. I know how the interview process works. All these big corporations optimize their recruitment processes around pedigree (matched to the curriculum of top universities). They don't look at track record at all; when track record is a far better indication of future performance. That's why their engineers are so incompetent and it costs so much money for them to produce anything.
They have become so incompetent that they don't even have the talent necessary to know what talent looks like when recruiting.
Corporate engineers will never hire other engineers who are better than them (for political reasons), so the engineering talent in these companies has been degrading for years as the bureaucracy and internal politics has increased.
