One of my close friends studied CSE at the Heritage Institute of Technology Kolkata. According to her, they have a great faculty, well-maintained infrastructure, and an updated curriculum.

Heritage Institute provides better placement opportunities than UEM and CIEM Kolkata. It also offers good industrial exposure to its students through various kinds of workshops, seminars, and guest lectures.

UEM is a very new college so it cannot be compared with old institutions like Heritage or CIEM.

It is suggested that you go for Heritage Institute of Technology rather than CIEM or UEM in Kolkata. It will provide better prospects for your career.
