Maybe you two should compare where you work and what you do; Google's a big company with over 72.000 employees, it's highly unlikely everyone has the same experience worldwide.
Exactly, two engineers could have an entirely different experience based on their team. Engineers can transfer to different teams too, though that team will obviously look at the engineer's history of performance.
Two engineers on the same team can even have vastly different experience. Google is big enough that it attracts a huge spectrum of engineers and one person's hellish workplace is another person's bliss.
