Someone else's package doesn't guarantee that you'll also bag the same package. Out of mentioned options, NIT Patna is a better option not because of the 40 lakh package. The placement package had been offered by Adobe which is said to recruit 2 ladies each offering 20 lakh packages to each. But in 2018, Adobe hired a female student offering her 40 LPA package, which can be true or even wrong information. However, you should not take admission in NIT Patna just because someone bagged a 40 Lakh package. The package will depend on your dedication during the course. It will help you easily earning a 6-8 LPA package.

While there is no doubt that NIT Patna is an old institution, yet it lacks some of the basic facilities such as hostels and open spaces. The campus is quite small as compared to other engineering colleges. So, it does not feel like a proper campus to some students as they have to spend 4 years there.
In the present time, a mega hostel is being constructed but it is outside the campus. The locality surrounding the campus is very unpleasant.The good thing is that the campus is located beside Ganga, having some modern and beautiful ghats. The management and staff are strict and less creative.
