M.Tech Industrial Management

Hi All,
Here's seeking suggestions and feedback.
I got interview calls for M.Tech in Industrial Management from ISM, Dhanbad and BHU, Varanasi. I want to know
1. How is the interview conducted in these colleges in terms of type of questions asked, etc? and
2. This course is better in which of the two colleges?

I am an E&C grad of 2007 with 2 years work ex in Infosys.

Any pointers reagarding this will be great help to me.

Thanks In Advance..

Warmest regards,
Biplab
