Google's Hiring Strategy

I found this reference to Google's hiring strategy. Google relies on the Lake Wobegon Strategy, which says only hire candidates who are above the mean of your current employees. An analysis of the simulation over time, using this strategy shows how good it is (the blue line). An alternative strategy (popular in the dot-com boom period) is to justify a hire by saying "this candidate is clearly better than at least one of our current employees." -- red line. The orange line corresponds to the no hiring manager strategy, in use by Google.
