Hi,

Top recruiters like Amazon, TCS, Wipro,Infosys,etc approach colleges only when they're interested in hiring students. They first verify the college and the courses offered there and also they take interviews to know how well the student is aware with their course and how they are going to tackle real life problems. These companies hire those students who qualify the interview. The college you're referring to offers great training to the students to crack the interviews which makes it easier for the students and for the conpanies as well and they do respond better towards placements.

I hope this clears your doubt,

All the best
