I have 2 friends who work at the Amazon office in Denver. Both work on boring projects utilizing internal tools Amazon built over the years and completely hate their lives. But the salary and stock options make them stick around. You can look at this as "Omg, this is total shit. I'd never want to work here." or "I don't mind suffering 4 years to get fully vested, get the fuck out of dodge and enjoy retirement a little earlier than others." Both of my friends picked the latter.
