Hey Mayank

I will brief you up on all the three options so that you can decidefor yourself as to which one is better.

LMNMIIT- It is an excellent college. The faculty is well qualified and the curriculum is good enough to prepare the students for the industry.Almost 90-95% of the students get  placed in CSE department. The average salary package offered for this year's batch ranged between 10-12 Lakh per annum

IIIT Kota- The infrastructure of this college is amazing and so is the faculty and the course structure. The highest package and placement percentage is of CSE department but around 75% of the ECE department students get placed too.  The average package is around 8 Lacs. whereas the highest package goes to 29 Lacs.

MSRIT- According to some of the students only a few core companies(You get around 8 to 9 core companies ;and around 8 cgpa to qualify) visit the campus. To get placed one will need to learn  C, C++, Python Script, Java. The infrasturucture is really good and the course curriculum as well as the faculty is student friendly. Even though the placement percentage may be low  the highest package from instrumentation technology in TCS was almost 32 lacs per annum.
