It would be really interesting to do a study of Googlers and see how much time on average they spent preparing for the interview. Would also be interesting to compare that with average preparation of people who interviewed but didn't get the job. And finally, it would be fascinating to plot career performance at Google vs time spent interviewing. Intuitively I would expect those who got an offer without studying to do better (higher latent intelligence), but I could also see it going the other way (lots of studying correlates with willingness to work hard on boring problems, which is what most Google engineers actually have to do day-to-day).
