Which MBA specialization should I choose in MBA after doing B.Tech?

Yes, it is a good option to do MBA after B.Tech, but you should have interest and proper skills or should develop skills like communication. All the best for your bright future.

Dear, If you are really interested in managerial job and already completed your engineering degree i.e. B.Tech, it is always a better option to pursue MBA after having a work experience of 3-5 years. Yes, you are to do it from a brand B-School after cracking management entrance exam. Best wishes.
