I'm courios about the salary offered. In Amsterdam Booking is known to be paying above the market average. Their salary range is also listed stack overflow careers page. Are salaries really that hight in India?
If these engineers want to move abroad, they'd usually prefer the US because salaries there are significantly higher.
But even if you have good skill set, but don't want too much pressure and would like a fairly stable at some Indian consulting company, you might only be drawing around 30k USD. But you get to earn if you are sent for an onsite assignment.
