I just completed my B.E in mechanical engineering and now I'm confused of what to do next. whether M.Tech or MBA ? which is the best option

If you are interested in Higher Studies or research in the same stream then you may go for M.Tech. you should have 55 % in B. Tech/BE and a valid score of GATE. I am enlisting a few good colleges for Mtech : IIT Roorkee, IIT Guwahati, DTU, IIT Varanasi, IIT Dhanbad, NIT Surathkal,NIT Tiruchirappalli, NIT Warangal, NIT Calicut, , Lovely Professional University, Jalandhar ,Punjab, College of Engineering, Anna University,DTU,VIT, BITS, IIIT Hyderabad, IIEST Howrah, College of Engineering Pune, Jadavpur University, IIIT Allahabad,Anna University

If you are not interested in learning technology anymore, only then you should pursue MBA . You should have cleared anyone entrance test ( such as CAT/MAT/XAT/NMAT/CMAT/GMAT/NEST ) and should also have a min of 45% to 55% in your bachelors .you can do MBA in any specializations of your interest. Some Good Colleges are: IIMs, XLRI

Goa Institute of Management

Lovely Professional University-Punjab

K.J. Somaiya Institute Mumbai

D.Y. Patil University

Both are good fields. One is east another is west. We cannot compare both. It all depends upon your interest. If you liked what you studied in B.E degree and have an urge to know more about it, then do M.Tech from a good college and after that there are a lot of government job opportunities lying there. If you think you have wasted your four years doing a B.E. and now want to shift your career to the business or corporate world, then you should consider doing MBA, but only from a good college.
