I have a few friends at Google, all of whom got in many years ago. They all claim the interview has gotten a lot harder, and that there's no way in hell they'd pass the current level of scrutiny. Although FWIW, they also say they also would not have passed the interview for the time period they got hired if they had to do it again a second time.
