My colleague did his B.Tech from NIT AP and here are the insights he shared with me about NIT Arunachal Pradesh

PROS:

Placement: In 2020, the placement rate of NIT Arunachal Pradesh was 38.53% placement as 42 out of 117 students got placed under different sectors of the industry. 

• The highest package offered was INR. 12 LPA. 
• The average package offered was INR. 6.2 LPA. 
• Some of the top recruiters who visited the campus were Capgemini, Infosys, L&T Constructions, Cognizant, Vedanta, CGI, KEC International, etc.

• Ragging: NIT has an anti-ragging environment. Seniors are in fact very helpful and friendly.
• Faculty: Professors at NIT are average as they lack knowledge and qualifications but they are very student-friendly and keen to help you.
• Internet connectivity: The campus is equipped with unlimited high-quality Wi-Fi.

CONS:

• Infrastructure: The campus is small and not at all student-friendly.
• Facilities: Labs and other facilities are not satisfactory.

So, if you just need a degree you can join NIT Arunachal Pradesh but if you are looking for a college with high facilities like campus, labs, etc then there are colleges better than NIT AP.
