Most Government, as well as Private companies, prefer BTech graduates to MTech or MS graduates. One needs an MTech degree only if one wants to enter academia or research. The reason they prefer a fresher is that they consider them flexible and thus sponsor them for higher study in their field of requirement.

M.Tech degree is not required to secure a good job and I will recommend you start preparing for GATE instead and target a PSU job. The written tests and interviews during the process of GATE Preparation will increase your chances of selection in the future.
