I have done civil engineering. Which specialization should I choose to pursue MBA?

This would depend on your interest areas and career aspirations. You need to refer their curriculum & keeping in mind your interest areas choose the one that suits your interest areas.

Well, related to civil, there is no any specialisation in MBA. But you can go for your interest in any stream in MBA like HR, Operations, Marketing, Finance and many more. If you are interested in technical education related to civil only then you can go for ME or M.Tech.

Hi, It totally depends on you. As with civil, there is no specific MBA. You can try MBA in any stream. If you want a career in sales and marketing then go ahead with marketing or else HR, operations, etc.
