I have a friend who recently graduated in CSE from DIAT. According to her, DIAT fails to offer good opportunities to the students. It’s better to choose newer NITS. 

• Even though DIAT comes under the Ministry of Defense, the academics and facilities offered at the institute are not up to the mark.
• The teachings, non-teaching as well as administrative people are not cooperative with the students.
• Moreover, the placement cell doesn’t bring companies for placement as expected. They don’t even bring software companies like TCS or Infosys for placement.

So from this, you can draw an overview of how things are at DIAT. You can go for NIT Durgapur or NIT Goa. Even if you don’t get NITs, try for Government College of Engineering, Pune. It has better facilities and placements.
