Hello Aspirant,  for the maximum salary you have to choose the M.B.A field. You have to done your M. B. A from IIMs so after completing your M.B.A you will get the highest package upyog 60 lakh to 1 crore or above. But only one one of the best student can get the placement. 

I hope this will help you. 

Cos. like microsoft etc pay 75+L for principal data scientists etc., and most of these guys are PhD. Most of those PhDs are from sadakchap universities though, but still they have a PhD. They were lucky enough to not have cleared that coveted engineering admission, and thereby, settling for that BSc course, which eventually is giving them much higher return than those BTechs.
