Hi Ankur, 

Whether you should pursue MBA or M.Tech in future depends on your interest and life goal. If you are looking for core engineering job then either you can go for M.Tech or you can join a firm related to your core specialisation. But if you want to work in non-core or management firm then MBA is a good option. MBA in IT is again a specialisation. It depends on your interest and firm type you want to work in future (FMCG, IT, Consultancy etc.)
