Colleges in Tripura

Sorry, you won't get NIT-Warangal but you may get any other NIT.

Job prospects are average in NIT as the chances are not that higher but still there are chances for placements.

IIT - Delhi is the best institution for Ph.D in computer science.

NMIMS is a globally recognised brand and highly recommended for distance education for its presence and awareness amongst companies and curriculum designed is industry oriented.

Dear Prasenjit Deb,
NIT-Agartala is the best option when compare with Silchar. NIT-Agartala received (last year) 36 LPA, whereas Silchar received 9.5 LPA, you can prepare for NIT-Agartala.
All the best.

Be calm during your GDPI. Present yourself as exactly as what you are. Don't pretend to be so professional. Have your own answer and not bookish and take it as a fun. If you get nervous, interact them with your life amazing moments. It will be a perfect one. Go through some current affairs and nothing more.

NIT-Agartala is a good option and has been a good brand with very good industry oriented faculty and curriculum. NIT-Silchar is bit new and nascent and hence, does not have an edge.

Dear Prasenjit Deb,
NIT Agartala offers 100% placements. Placement packages were between Rs. 15-20 lakhs per annum for MBAs. A number of companies visit this campus. All the best.

It will not be right to quantify which institute is better between the two that you have mentioned, especially because this can be different for different individuals with different requirements. Having said this let me also state that ICFAI is more famous among both students and employers as compared to the other in my point of view.

HBTI is surely a better option to pursue electrical engineering
