"What's your stream? You didn't mention it but I would suggest to go for core domain MBA program matching to your current qualification. There are various industry focused MBA programs available like MBA in Oil & Gas Management, MBA in Urban Infrastructure & Development, Aviation Management, Power Management, Port & Shipping, Logistics etc and A management degree in these domains are really great for engineering graduates. You can pursue such programs in UPES plus there are some other institutes which have some of these courses like Institute of Logistics & Aviation Management or Indian Institute of Logistics which offer some of the above courses but still UPES is best for core domain MBA. You can apply for UPES as admissions are open in the university for MBA."
