The worst I could say about the India based teams I've worked with is that some were to-the-letter to a fault. Anything not explicitly stated was skipped, where you'd typically expect a dev to fill in the unstated but obvious things that you only discover while working a task.

But that was at Amazon. At my current gig, the India based teams are great. Not quite up to the standards of the US teams, but I'm sure they're more cost effective. They're also hungry for more interesting responsibilities, and are proactively improving things. It makes me think that Amazon just had shitty management over there.
