A few years back, a friend of mine was in a position to choose between lower-ranked NITs and AMU. He chose the latter and based on his experience, he swears by that decision. He later went on to do this postgraduate from NIT Warangal.
Here is his take on AMU and NITs.
However, not all NITs have a better placement record than AMU. The bottom-most NIT’s according to placements and academics are as follows.
NIT Sikkim < NIT Mizoram < NIT Manipur < NIT Arunachal Pradesh < NIT Nagaland < NIT Meghalaya < NIT Andhra Pradesh < NIT Puducherry < NIT Uttarakhand < NIT Goa < NIT Delhi
Where NIT Meghalaya and NIT Andhra Pradesh(NIT Tadepalligudem) lack in campus also.
