TBH Amazon Indian org is known (from the Seattle folks I spoke to) for being sub-par filled with employees from service companies, so no surprises there.
But yeah, the talent here is good since hiring talent is cheaper here compared to US. If you have to pay 170k$ to hire the best in US then in India you'll be able to hire the best at 50 LPA which is about 70k$.
I have been part of many interview panels and they haven't been any easy interviews as such.
