UPSC, Indian MBA, or MSBA (ASU): Which path offers the best long-term career prospects?

I am currently in great confusion, I do not know what to do next: study for UPSC or do an MBA in India or should I pursue a Master’s in Business Analytics from Arizona State University?

First of all, you need to be clear regarding what you want to in future, the career prospects which you have listed are varied and have different career pathways. All I can do is give you the realities of each option and you can figure out what makes sense for you. Rest you have to figure out whether you want to take up challenges of improving the system and earn good perks/power/respect for it OR you want to work hard, spend less time with family and have luxurious life.
