My question is if the candidate did a degree at a good school doesn't that prove anything? If they did a similar job for a competitor that doesn't count or has a giant set of github repos does that not count? My feeling is that pressured puzzles are a cop out unless you are trying to filter out low level employees. Also your comparison with share price is not necessarily accurate - #1 company in the past 100 years is Exxon (profit per 100 years). I would argue that they manage their existing employees better than their competitors and fire the weak ones. In 50 years I'll bet no one knows facebook or google - just like no one knows DEC or any other tech company from the 70s except IBM and Oracle. Currently they just have the Zeitgeist going for them.
