If you are considering pursuing a course in Data Science at NIT Trichy, it may be helpful to understand the differences between the Computer Science Engineering (CSE) and Computer Applications (CA) departments. While both departments offer courses in this field, the quality of education and faculty expertise may vary.

It is worth noting that the CSE department at NIT Trichy has been facing a shortage of proper faculty, with some important undergraduate courses being taught by temporary faculty members. This lack of expert faculty in the Data Science domain may be one of the reasons why the course is offered by the CA department instead.

To gain a better understanding of the academic and research profiles of the faculty members in the CA department, you can refer to the institute website for more information. This can help you make an informed decision about which department to choose based on your interests and career aspirations.

It is also important to consider the placement opportunities available after completing the course. While it may be true that certain companies hiring for PG students may not differentiate between candidates from the CSE and CA departments, it is still worth researching the placement records of each department to ensure that you are making the best decision for your future career prospects.

Ultimately, the decision of which department to choose should be based on a variety of factors, including the quality of education, faculty expertise, and career opportunities. By doing your research and carefully weighing your options, you can make an informed decision that will set you on a path toward a successful and fulfilling career in Data Science.

IISC Bangalore introduced the M.Tech AI program in 2019. It is offered by the EECS division. 

For the curriculum,  the basics of optimization, linear algebra, probability, data structure, and algorithms are covered during the first semester. 

M.Tech in AI is different from M.Tech in CDS in terms of core courses. The electives offered in both programs are almost the same.

The IISc Bangalore tag will be very useful in case you go for your Ph.D. in India or abroad. But for that, you need to maintain a good GPA.

The 2021 placement highlights for M.Tech AI (both off-campus and on-campus) are as follows, this was the first M.Tech AI batch-

All the students were placed. The offers received were Indian.

The CDS, CSE, and AI branches receive similar placement and internship opportunities. The students of all these branches receive offers in data science, machine learning, and software engineering.

Thus, M.Tech in AI at IISc Bangalore is a good branch in terms of placements and prospects. It is similar to the CDS program in many aspects. 

I completed my M.Tech CSE from IIIT Bangalore some years ago. This makes me eligible to answer your query.

Here are some reasons why this degree is more beneficial for your career than simply switching jobs-

1. As an M.Tech CSE graduate from IIITB, you’ll be offered much more than 11 LPA. You can expect to get around 15-16 LPA as your starting CTC.
2. Top companies like Microsoft recruit from the IIITB campus.
3. Companies like TCS have very low workloads, and the work is mostly brainless. This can make you lazy. An M.Tech course will help exercise your brain.
4. It’s difficult to switch from service based companies to product-based MNCs. You may end up in a service based company or a product-based startup post-switching.
5. M.Tech graduates from IIITB are much more likely to get into a product based MNC. 
6. The college tag will open more opportunities for you career-wise.
7. You can access good off campus opportunities as Bangalore is the ideal place for tech professionals.
8. At college, you’ll spend your time studying AI/ML, and developing your coding skills. 
9. You may not get to develop these abilities at your workplace. They may give you basic support projects, excel sheet work, etc. Then you’ll have to develop your coding skills post work hours. 

Thus, I would recommend you consider an M.Tech CSE from IIITB instead of relying on a job switch.

It's difficult to say if IIIT Hyderabad MTech or MS CSE is the best or not as it's a matter of personal preference. What might be best for you, may not be for someone else. So first, you have to identify your interests and goals. Usually, IIIT Hyderabad is suitable for 

• People who want to pursue high-level research in CS
• People who are determined to pursue a career in CS and want to polish their CS skills and fundamentals
• People who are just after the IIIT and CS tag

Every institute has something or the other to offer so comparing them isn't right. Instead, look at the bigger picture and understand what you are looking for in your degree and which institute will serve you best.
