Students at PDPU are encouraged to pursue research and taking up 4 to 6 weeks for an internship is compulsory so that knowledge can be applied in a practical setting. At DDU, research work is encouraged. Tests are conducted on weekly basis to facilitate learning. Students are taken on various field trips by both universities.

Placements:

Over the years the placement opportunities at PDPU have remained the same whereas the fees have increased considerably. Placement opportunities at DDU have increased over the years.

• At DDU, companies like TCS, Infosys, Amazon, Apollo hire students every year. The average salary packages offered are around 3.5 lakhs per year. 
• PDPU has a training and placement cell that has ties with national and multinational companies. The average salary offered is around 5 lakhs per year.

ICT offered by both PDPU and DDU is good. Both colleges have their own advantages. Deciding which college to opt for depends on each individual’s expectations, resources, feasibility, and goals.

According to the NIRF India Ranking 2020 for the B.Tech course, KLE Technological University ranks at 136 out of 300 colleges in India. It is also the 16th best university in the state of Karnataka. KLE Technological University offers a BE program for these specializations and the admission is through COMEDK-UGET or KET.

Electronics and Communication Engineering:

The course enlists practical training, site visits to NASA participation as an essential part of the curriculum. 53 faculty members are in the department.

Placement:

• In the year 2019, 210 students of the ECE department were placed in well-known companies.

• Mercedes Benz R&D, Toyota Kirloskar Motors, Tata Motors, Applied Materials, L&T, JSW (Jindal Steel), etc are some profound corporate companies hiring from the ECE department.

Mechanical Engineering:

Mechanical Engineering has a flexible curriculum course overlooking Design, Manufacturing, and Thermal streams pertaining to present-day Mechanical Engineers. There are 62 faculty members in the department.

Placement:

Electronics and Communication Engineering has a wide scope in consumer electronics and IT industries. A Mechanical Engineering degree has prospects in manufacturing units, aircraft as well as other industrial machinery. Automation as an industry has good potential in nuclear science and the formulation of bio-medical equipment. It is recommended that a student should pursue the course of his/her choice.

Having to know some people studying in these colleges and after reading some reviews online, I can say that market calculations for placements might have changed. But I could assure you that any of them would give solid infrastructure, reasonable learning experience, and plenty of opportunity for placement. 

Herewith I'm briefly differentiating all the colleges you mentioned :

Choose one that meets your needs, taking into account other aspects such as costs, distance, etc. But it is better to take LNCT as your first preference at private school and to obtain entry in IT or CS out of the 1994 seats available.

This will entirely depend on your interest as you are comparing two different colleges and two different branches. If you are interested in one particular branch, don’t decide between the two colleges as they are both NITs.

You should first see where your interest lies and choose an option accordingly. If you are not sure, I will suggest you take CS in NIT Patna which is the better option. Here are the recent placement highlights for NIT Patna. 

Regarding civil engineering, let me tell you that even if you land up at an NIT, you will have to prepare for GATE or ESE exams since the placement scenario is not that great.

With civil engineering, you will have to do a lot of hard work but with CSE, you will be able to enjoy college life and get good placements at the end of your degree unlike civil. 

In the end, it boils down to your interests and what you are looking for.

There’s no doubts about the fact that 5 years at IIITA is a smarter option compared to anything else. This is because of the simple calculation that you are going to study the same curriculum for 4 years BTech for 3 years. That is all about the core of CS and IT. One core and two electives are a part of the fourth year in a 4-year BTech program, which hardly makes any difference. 

According to the experts, Robotics is the future of the IT industry and hence, finding yourself in the midst of such an academically enriching atmosphere which ensures a full time access to a premium robotics laboratory and esteemed faculty will certainly do good to you in more ways than you can ever imagine. That’s the kind of right exposure you are looking at.

Moreover, this department at IIIT Allahabad is being funded by MHRD, thus having a lot of helpful and positive influence from the big academic and administrative circles from all over the country. A number of international conferences sponsored by IEEE are held here regularly. A DST funded summer school of robotics is also a part of this institute. IIIT Allahabad is known to have multiple MOUs with various popular foreign universities and has extensive student exchange programs to give the best exposure of the industry and experts to its students.

My brother had the option of VIT for CSE on merit still he chose PEC metallurgy. There are various reasons as to why he took that decision:

• VIT is more expensive. Even if he had gone on merit, it would have cost him much more than PEC.
• Placements in core companies in ECE are negligible. You can sit for IT companies, but they pay less to ECE undergraduates than CSE counterparts.
• If you are a north Indian, culturally VIT might be different and might take time to adjust.
• Metallurgy is an undervalued branch in India; many of my seniors are pursuing MS from Germany, the United States, and France, and some have gone to IIMs and FMS with strong credentials.
• One of our seniors received a PPO of 15 lakhs, which is more than many students from elite branches.
• You can choose to upgrade, but you'll quickly realize that it's not that simple because the grading criteria favors those who are less deserving (no offense).
• Whether you accept it or not, those who claim that placement in metallurgy is poor (as it is in all branches except CS/IT) are correct. Placements in the core are hard to come by.
• Only 4000 people in GATE are from metallurgy, whereas there are 1.8 lakh from CSE and 2.1 lakh from Mechanical, implying that the probability of you getting a PSU is greater than that of a mechanical engineer.

I personally believe VIT is overrated because a friend who did not even pass mains received 2000 AIR in VITEEE. In the CBSE 2016 boards, he scored 78 percent, which was below average.
