Should IIT Patna be preferred for an M.Tech in CSE? Are NIT Tirchy, Warangal, Surathkal better than IIT Patna for an M.Tech in CSE?

Yes, NIT Trichy, Warangal, and Surathkal are better options for MTech than IIT Patna because of their superior location. The placement scenario at any institute is directly proportional to its location and proximity to tech hubs. 

A location imparts better industry exposure that forms the foundation for any tech college. Consider the location as the primary factor while choosing your college. The reason I said NITs are better than IIT Patna today is because of their location and the quality of recruiters they attract as a result. 

IIT Patna is a great institute but lacks the recognition yet and thus most recruiters don't visit it. So, look beyond the IIT tag a make a wise decision.
