IIT BHU offers Phd programs to students who have a knack for research and development.
This answer is based on my experience of the current market. A Phd. from a top branded institute is good, but you’ll have to market yourself.
The employers search for candidates who have clear goals. They will try to figure out why you choose a certain subject and college and your past achievements, among other things.
Try to have a look at the placement figures of IIT Tirupati for Phd., and consult the faculty members in this regard.
Brand name has its own value, but you must have a good grasp on your subject to clear interviews. This applies to any branch or college student.
BRABU takes admission for PhD based on the performance of students in the aptitude test - PAT. UGC NET or JRF qualified candidates can also apply for the PhD program. UGC or JRF-qualified candidates don’t need to appear in PAT to get admission. BRABU PAT 2022 dates will be announced soon.
