Both are great institutions in terms of academics and in terms of placements too, but there are some major factors that make IIIT Bangalore better than NIT Surathkal.

• Hygiene at campus and hostel: Both the hostel and campus of IIIT Bangalore are very clean. As cleanliness is very much important for all of us the hostel and campus of IIIT Bangalore are well maintained which is not the case at NIT Surathkal. This is very important for all of us and cannot be neglected.
• Study Curriculum: The study curriculum of IIIT Bangalore is very much up to date and it has all the important topics and syllabus which is important in today's world and will be helpful for the students in their future. 
• Admission based on merit: The admissions at IIIT Bangalore are completely based on the student's merit and there is no influence of other factors like caste, gender, management quota, etc. Students get admission based on his/her JEE score.
• Good research and industry opportunities: This college provides good research facilities to its students and the prime location of this college also helps to get more focus and attention which plays a major role to get further opportunities to its students.

But there are few demerits of the college too like - 

Life at this college can be difficult which is similar to many colleges in our country, as the environment there is not that fancy like it is shown in our movies but one can get used to it after spending a few months.

The college fest is not that great and interesting as compared to other colleges where the fests are organized in a grand way but this is slowly improving as both the students and the college are putting in efforts to make it better.

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.

One of my friends graduated from NIT Trichy and here is some information about the placement scenario that I gathered from him. You may find these useful also.

• M.Tech program in Computer Science is aimed at providing a comprehensive overview of the recent developments in the various frontier areas of Computer Science. 
• These include Computer Architecture, Software Systems, Parallel and Distributed Computing, and Networking, and Web Technologies.
• A sufficient amount of theoretical input is also given to the students. 
• The students will have ample opportunities to carry out software development using the modern computing facilities available on the campus.
• To attract good students 5 GATE scholarships are offered to eligible candidates. 
• Students who complete the program are employed immediately as Systems Analysts, Software Engineers, or Computer Engineers in the industry. 
• Alternatively, they can pursue higher studies in institutions of repute in India and abroad.

Many reputed companies participate in the placement program. These include - TCS, Infosys, Facebook, Capgemini, Morgan Stanley, Cognizant, Accenture, IBM, Wipro, and many more. You can check the official website of NIT Trichy for a complete placement record.

My brother has completed his M.Tech from MNNIT Allahabad and according to his experience, this institute lives up to the expectations in terms of placement. Here’s why:

• If you have done enough justice to your studies during these 2 years of M.Tech, then the rest is assured. Although no specific CTC can be guaranteed, you will ultimately land a good job.
• No doubt MNNIT Allahabad’s placement cell is very active and works hard for your better future. Thus, a long list of companies usually visits for campus recruitment every year offering a plethora of opportunities.
• In my brother’s placement time, companies like Walmart, Sony, Cap Gemini, TCS, Samsung, Amazon, Directi, etc companies came for recruitment. However, you must be efficient at coding to grab decent packages in such big companies. Here also, MNNIT help you out with their bunch of bonafide students that take the "ComputerClub" classes.

Overall, if a placement is your goal, you are at the right place. Luckily if you belong to the CS branch in MNNIT or any other college in India, you can have one of the best placement packages. Most of the students of the CS branch get placed for jobs and internships too.

The Alumni network is the most important factor of placement statistics and MNNIT Allahabad has one of the best alumni networks.

Delhi provides you with nightlife whereas Allahabad does not. Allahabad is not a metropolitan city like Delhi. If you want these two things, MNNIT is not for you. But it will definitely provide you with great learning opportunities. You can enjoy yourself a lot with your friends, more than you expect. Hence, it does not become less enjoyable just because it lacks nightlife and the tag of a metropolitan city.

Transportation matters a lot when it comes to placement drive. HR of reputed MNCs don’t have enough time to travel via road or train for recruitment purposes. Despite not having an airport before, MNNIT Allahabad has managed to keep its placement statistics outstanding. 

For CSE the most popular choices among students are as follows. 

1. IIIT Hyderabad
2. NIT Trichy
3. NIT Warangal
4. MNNIT Allahabad
5. IIIT Allahabad

So, CSE from MNNIT is one of the best. You can definitely consider it as a valid option. 

When speaking in terms of placement records, IIIT Allahabad is known only for B.Tech. However, M.Tech at the same institution tends to not get great offers. In fact, most companies do not permit M.Tech students from IIITA to sit for specific interviews. 

Companies like Microsoft, Amazon, Hashedin, Morgan Stanley didn’t allow M.Tech students to sit for the interviews one particular year. That is one reason behind why IIIT, Allahabad does not make the placement stats clearly open in a branch-specific manner.

You, as a student, should prefer M.Tech at NIT Nagpur. Mentioned below are the statistics of M.Tech placements of VNIT Nagpur. 

It is important to note that MTech IT (i.e., Intelligent Systems) is very well known at IIITA. If you are choosing to do Intelligent Systems at IIITA, then you will not regret that decision. You definitely will have the chance to sit for every company interview. However, if you do not get Intelligent Systems, then opting to go for NIT Nagpur is highly recommended.

In terms of placement, the preference order of branches are as briefed below:

Intelligent systems, IIITA> CSE, VNIT Nagpur> Advanced computing, NIT Bhopal> Information security, NIT Bhopal> Human-computer interaction, IIITA> Cyber Law IIITA> Software Engineering IIITA> Wireless communication IIITA.
