DTU, earlier known as DCE, has a rather obsolete curriculum and pedagogy. Despite that, it invites more than 450 recruiters every year. These companies are well aware of the excellent coding culture at DTU showcased through the student's online presence on top sites like HackerRank/HackerEarth/Codechef. So if you are a coding lover, DTU has opportunities at par with top institutes like IIITH, IITB, and BITS Pilani.

However, rankings are done on various aspects including GO. Considering all the branches of DTU, it rightly deserves to be among the top ten due to its location. 

But NIRF ranks it poorly as it considers a variety of parameters like:

• TLR, Teaching, Learning, and Resources: DTU has very few approachable faculties thereby bringing down the ratings
• RPP, Research and Professional Practice: Recently, DTU has received funding so it’s slowly improving its research culture which earlier was non-existent.
• GO, Graduation Outcomes: DTU has a good graduation outcome almost comparable to IIT Bombay.
• OI, Outreach, and Inclusivity: This brought down the rankings miserably. 

So we can conclude that NIRF rankings are based on useless criteria and shouldn’t be considered to evaluate colleges worth and credibility.

It’s hard to determine the worth and credibility of these institutes just by looking at official rankings. So I will be taking into consideration some criteria 

• Placements: The placement scenario and opportunities offered at all these institutes are equally good as similar companies visit for placements. Companies like Google and Facebook conduct an open test like APAC so students of all institutes get equal opportunities.
• Campus life: In terms of the campus and city life offered, my preference order would be DTU = NSIT > NIT. Being in Delhi, NSIT and DTU offer better opportunities and exposure. Delhi has it all, major corporate headquarters, the media, and top colleges like IIT-D and DU to compete with.
• Student pool: The peer group has a massive effect on you and helps you in determining your interests and activities and grooming your personality. The ranking of colleges depends solely on the type of crowd you are looking for. If you are from south India, you would prefer to join NIT- Trichy. So this aspect cannot be generalized at all.
• Campus: A dynamic college life is very important to break from occasional strenuous situations. In that aspect, NIT offers the best campus life followed by DTU and NSIT. 
• Faculty: The faculty pool is better at NIT than at NSIT and DTU. NIT is a central government institute and has a better recruitment process so filtration is better.
• Alumni: Alumni network plays a big role in your institute’s reputation in the corporate sector and can help you financially with your startup idea. That being said, DTU and NIT Trichy have the best alumni network followed by other NITs and NSITs. 

It’s best to go for the college that is best suitable for you alone and not just because it has good rankings.
