hello aspirant,

mechanical engineering is almost dead in todays's time, but this doesn't means it's a bad option either. If you have interest in studying it you can do wonders in it, it just depends on how much you fight for it. so please think once before going for mech in MNIT jaipur, because if you have MNIT mech u may also have some option for ECE, EE in other NIT's or maybe CSE in some colleges which are great.

coming back to your ques, it is average like any other college with average placement of 5lakh/anum,with good facilities and environment.
