Hello aspirant,
First of all, the universal truth is that packages always differ in different institutes.
Starting package is 30-35k per month (maximum) and after that it will increase.
If you are thinking to do your masters from IHM then you can expect a handsome package.
Generally, as a trainee you will get a stipend of about 21,000. IHM Mumbai offers 31,000 for trainee (highest).
If you get placed in ITC, you can expect around 40-50k  based on your experience.
If you have talent, no need of good college tag, big companies will offer you big packages for your talent, not college name.

Hope this answers your query. Good luck!
