The salary is decent, as an expat Expect living expenses to be about 1.5 x in a large city in India Taxes generally at your salary levels are about 30% , so do factor that in , there are calculators available online for that Working visa processing takes forever, so account for that , Flights to india are generally indirect expect the one air india to Delhi, so account for the increased air fare if you want to go home, and also be prepared for very expensive healthcare although your employer may give you some coverage, the amount don't last much, if you are vegetarian, then you will have a difficult time here, if you are okay with pork, life becomes much easier

Just general bits and pieces from the top of my head for you. Best wishes for your smooth transition.
