I worked at Amazon India (Retail, not AWS) for about two years straight out of college and experienced pretty much none of the issues described in OP (maybe with the exception of the delayed vesting*) I had the opportunity to work with some pretty smart people (whom I'm still in touch with), on great projects, with manageable oncall, and a good manager who didn't micromanage. In my time there, not a single person in my 40-50+ org was fired. If anything, the problem at Amazon India is that there are too few senior engineers, as most leave for better opportunities in Seattle or at other companies (since better/more important teams and projects tend to be located in Seattle.)

* Something the original post fails to mention is that this difference is made up for by a fixed joining bonus that is roughly equal in value (or at least it was, for me.)
