How fruitful would it be if I preffer MBA after B.TECH??
Many have suggested me to opt for M.TECH but i am interested in MBA.
I'd suggest reading our existing discussion on the topic MBA Vs M.Tech Vs. MS Dilemma. You'll find lot of relevant information on it.
In general. MBA would definitely be useful only if you get into one of the top 15 MBA colleges in India. If you are interested in management; go for it. People's opinion doesn't matter because you should be in charge of your own career.
If M.Tech doesn't appeal to you, do not opt for it. Always go for the career option that matches your interests.
