Hello,
According to the ratings released in 2020, Heritage ranks first in the list of top private engineering colleges in Kolkata, whereas IEM ranks 2nd. As far as academics are considered, both colleges are good and both gives priority to infrastructure, clubs, overall academic schedules. But the major difference lies when it comes to discipline. IEM has strict disciplinary rules and an attendance of 75% is compulsory to be able to sit for exams. Or else, they make it a priority to send messages to your parents when you bunk classes.
Both colleges provide good placement opportunities if you are consistent in your studies. Heritage had placements from Amazon, Byju's, TCS, etc this year.
Hope this helps.
