If you follow the official website, in the placement section you will see no such packages given. Only the students those got placed are given. So there is no official info available.

Now as per online researches, the average salary package is around Rs. 8 LPA and may vary. Also some of the frequent recruiters in Heritage Kolkata is ICICI Bank, ITC, INDUSIND BANK, EMAMI.

I hope my answer helps. All the very best for your future endeavors!
