I would love it if Google spent some time re-interviewing a bunch of their current employees, to see how good their interview process is compared to random chance.

I know their best employees would likely pass the interview with flying colors, but my hunch is that there would be a large percentage of their employees that would fail. If they did a thorough analysis, my hunch is that their hiring process is likely determined by who their interviewers are, rather than who the candidate is.

I'm not bitter because I was rejected twice, but I do believe that their hiring process is a lot more random than what they believe it to be.
