Hello,

In terms of college,  ISM Dhanbad  stood far better then NIT Warangal.

And the field which you opting has almost nice scope in industrial recruitments domain. Though it opens a bright prospects for research which too you'll find lack of guidance if you are studying in India.

With all respect to engineering and college consideration, your order should be

NIT Warangal < IIT Dhanbad

Though the final and most crucial decision is always yours's

Wishing you all the very best for your future endeavors.
