Which is best, an M.Tech from IIT or PGDIE from NITIE? What is the career growth after industrial management comparing to an M.Tech from a top IIT?

If you are more inclined towards Mathematics and Research, then IIT will be a good option for you. You can end up working as a business analyst for an MNC.

In the PGDIE course of NITIE, you will come across management sectors rather than technical knowledge. You will also get acquainted with subjects such as Operations and Supply chain. 

• NITIE would be a fit for you if you want to pursue management in the future. It will help you in getting placed in the best FMCGs and a number of the most sought-after companies in India
• Management skills come into play if you want to pursue M.Tech from an IIT. The jobs that you will get after graduating from an IIT will be related to analytics and consulting. The salary from the core jobs is not much. 

The connection NITIE has with industries is far better than the IITs in the country and the fact that it is placed in Mumbai, the financial capital of the country, you will get lucrative opportunities to engage in work with the industries for weekend projects.
