All they've managed to bring forth with their epic hiring process (now the de-facto gold standard, worldwide) is an epic... arms race. The higher they set their "bar", the more desperately people will cram their heads full of Boyer-Moore, A*, and countless other algorithms they (and their interviewers) couldn't otherwise begin to care about.
Other than Avis, Airbnb, and the local hotels, it's hard to imagine who could realistically benefit from such theater.
