Hi Yuvraaj. When doing B.Tech in Mechanical you can also learn CAD and CAM software's which will be useful for your future. Get a certification from Autodesk which is very useful in your future. This can help you in your future too. All the best. Regards. Gijoo

MBA through IIM would put you in the league where high starting salaries are offerred by MNC's. Thereafter it will your skills, expertise and hardowrk which will give you the returns.
