How does NIT Trichy have 95% placement? Even IITs don't have that much?

The reason why NITs unlike other institutions are having more placements in comparison to IIT’s is due to their quality of students has increased in the market. 

• NIT has rich Research and development equipment and these things allow the recruiters to hire more candidates. But it cannot be said that IIT students have fewer placements than NIT. 
• Another reason for good placements at NIT Trichy is because of its location as it is nearer to Bangalore and Chennai and companies find it convenient to visit here.
• It also depends upon the placement service of NIT. NIT Trichy also screens its candidates before sending them for campus placements. 
• Those sitting for their placements have to undergo placement exams in their third year. These exams are conducted by the final year students of your respective branch. Those who get 60% or above 60% in their placement exams are allowed to appear in the campus placements.

One of my friends suggested that computer science students get much better placements in comparison to other branches. The average package is INR 6lacs per annum and the highest package to date is 90 lacs per annum.
