The CSE from all three campuses is extremely sought after and has a high reputation in the job market. They are often compared to IITs. The choice between the two is therefore a matter of personal preferences. 

Warangal gives a slight edge to Surathkal owing to its proximity to Hyderabad, the IT hub of India although the difference isn’t much noticeable. Surathkal has a slight advantage in terms of campus life and weather. It is the only college to have a private beach.

Ultimately, there aren’t any major differences between these colleges. If you want a better campus life go for Surathkal but if you want better academic opportunities go for NIT Warangal or NIT Trichy.

If you are considering a career in computer engineering or electronics engineering, there are a few things that you should keep in mind. While a college degree may be helpful, it is not the only way to acquire the necessary skills to succeed in these fields. Here are some important points to consider:

• Skills do not depend on college degrees: It is important to remember that skills are not necessarily tied to college degrees. Many successful computer programmers and electronics engineers have acquired their skills through self-study, online courses, and other forms of independent learning. What matters most is your ability to demonstrate your skills through practical experience and projects.
• High demand for skilled computer programmers: There is an infinite demand for highly skilled computer programmers with impressive TopCoder and GitHub profiles. These skills are highly valued in many industries and can lead to rewarding careers.
• IIIT-H is a top choice for computer engineering: If you do decide to pursue a college degree in computer engineering, it is worth considering the International Institute of Information Technology, Hyderabad (IIIT-H). This institution is widely regarded as one of the best in India for computer engineering, with a strong focus on research and innovation.
• Electronics engineering is the proper term: It is important to note that there is no such thing as "electronics and communication engineering" in the real world. The proper term for this field is simply electronics engineering. A skilled electronics engineer is someone who can use their command over low-level computer programming languages to make computers do what they want them to do.
• GATE/IES ECE syllabus is important for the government sector: If you are interested in pursuing a career as an electronics engineer in the government sector, you will need to follow the GATE/IES ECE syllabus to be able to compete in competitive exams.
• High demand for skilled electronics engineers: There is also an infinite demand for highly skilled electronics engineers with impressive TopCoder and GitHub profiles. These skills are highly valued in developed countries around the world, and can lead to rewarding careers.
• Two ways to become an electronics engineer in India: There are two main ways to become an electronics engineer in India. One is by competing in competitive exams to work in the government sector. The other is by getting recruited by private electronics engineering companies 

based on your TopCoder and GitHub profiles, even without a school or college degree.

In summary, pursuing a career in computer engineering or electronics engineering can be highly rewarding, even if you do not have a college degree. It is important to focus on acquiring the necessary skills through self-study, online courses, and other forms of independent learning, and to demonstrate your skills through practical experience and projects. Whether you choose to pursue a college degree or not, there is a high demand for skilled professionals in these fields, and many opportunities to succeed.

If I was to rank the above colleges, then the order would have been

1. BITS Goa(CSE)
2. DTU(CSE) 
3. BITS Hyderabad (CSE) 
4. NIT Surathkal(CSE) 
5. NIT Trichy(CSE)
6. IIIT Allahabad (IT)
7. NIT Surathkal(IT)
8. DTU(IT) 

Now, I am sure you would want justification for the above ranking so here it is

•  BITS Goa has the advantages of its Bits tag, excellent coding culture, has developed some great coders from the last 2-3 years, splendid location and amazing campus life.
• DTU is one of the best colleges in India with a decent coding culture and has the advantage of being located in the capital. Additionally, it has the advantage of an extensive alumni pool, location in the national capital, and a good alumni base
• BITS Hyderabad is almost similar to BITS Goa in all aspects as the placements conducted are centralized 
• NIT Surathkal and Trichy are the oldest and best NITs of India offering great placements, especially for the CSE branch.
• As far as the IT field is concerned, IIIT Allahabad is superior to all NITs except NIT Warangal, Surathkal, and Trichy.

Ultimately, the final decision is based on various parameters and personal preferences should be given due consideration.

JNU is considered to be one of the prestigious institutions in the country to pursue any degree. In 2019, the university secured 2nd rank among all the universities, approved by NIRF and NAAC ranking with A+ grade.

NIT Surathkal is one of the oldest technological institutions in southern India, rated as the best technological institution in Karnataka. In 2019, NIT Surathkal ranked 21st among top institutions in India as per NIRF ranking.

JNU:

Admission:

• For admission to MCA students need graduation with a minimum 45% aggregate and a valid JNUEE score.
• The students who enrolled in the course of MCA find it very competitive when it comes to the entrance exam. The majority of the questions will be from mathematics till 12th class, general aptitude, and basic knowledge about computer science. The questions will be in objective form with multiple choice answers.
• The cut off for the selection process will be based on the availability of seats and performance of students during the personal interview.

Placements:

JNU was mostly renowned for the highly consistent placement rate of 100% and the placement cell is managed by the students.

• In the academic year 2018- 2019, the highest salary package is 25 LPA, whereas the average salary package is 4.5 LPA.
• The top recruiting companies like Adobe, Microsoft, Google, Oracle, IBM, Wipro, TCS, Samsung, Infosys, Siemens, NEWGEN, etc.

NIT Surathkal:

MCA program at NITK is inclined more toward Application Development and emphasis on the latest programming language. The institute aims at producing trained professionals to meet the demands of the information technology industry.

Admission:

• Students need 60% marks or 6.5 CGPA in BSc/BCA/BIT or BE/BTech to be eligible for MCA admission.
• The selection of MCA is through NIMCET scores.

Placements:

The institute has an excellent placement record which is highly accomplished and well-placed alumni serving both within the country and abroad.

• During 2018 – 2019, 75% of students were placed with the highest package was 18 LPA, the lowest package was 3.5 LPA and the average package was 8 LPA.
• The major recruiters were Microsoft, Morgan Stanley, Oracle, Samsung, Goldman Sachs, IBM, TCS, Citicorps, Nokia, Dell, One Convergence, Radisys, JPMC, JP Morgan, Target Corp, Dolittle, etc.

Finally, consider the aspects associated with both choices and choose the institute which will be more convenient.

MCA program offered at both NIT Warangal and NIT Surathkal is highly regarded in the industry and there aren't any major differences between the two. Here is a general comparative analysis of both the NITs and their MCA programs

In general, NIT Warangal is better in terms of placements, crowd quality, infrastructure, and faculty. Both institutes, however, have a similar ROI. NIT Surathkal hasn't released its placement statistics for the MCA program, so I have mentioned that of NIT Warangal only. 

The placement percentage of NIT Warangal MCA placements stood at 96% while the same for NIT Surathkal stood at 88%. It clearly proves that NIT Warangal is a better option for MCA than NIT Surathkal. Moreover, in NIT Surathkal you will have to spend an extra year and spend extra money.
