Working for Amazon in India is almost like working for an entirely different company and is not a great comparison to working for Amazon in the US.

Cultural norms in the US apply in the US; cultural norms in India apply in India. I've generally found Indian managers and developers to approach the work entirely differently than their US counterparts. Not a negative--just an observation.

There does seem to be a pervasive undercurrent of "if I do good work on my team here in India, I can get out of here and go to the US as soon as my promo goes through". This sentiment naturally comes out in behaviour on teams and around coworkers.
