The placement opportunities for MTech in Computer Science and Engineering (CSE) at IIT Bombay are excellent and rightly so. 

IIT Bombay is one of the superior technology and Engineering institutes in the country. The placement procedure at IIT Bombay is extremely competitive, and recruiters from a wide range of industries and sectors visit the campus to recruit students.

The majority of the MTech batch is placed in top companies in the technology sector. However, the placement scenario is subject to change every year. Some students even receive offers from startups and other emerging companies in the technology sector.

The table below will give you a brief insight into the placement scenario of CSE at IIT Bombay.

Please bear in mind that placement opportunities depend not on one but a multitude of factors like individual skills, knowledge, and experience, as well as market conditions and other factors. So to secure the best opportunities, students should work and inculcate skills that make them suitable for the best roles offered.

ISI Kolkata is a great option for pursuing an M.Tech in Computer Science.  You will have great opportunities in Data Science and R&D. If you plan on doing a Ph.D. in Cryptography, this is the best course within India. 

ISI Kolkata M.Tech CSE placement profiles for 2020-21 included 19 Data Scientist profiles, 1 Machine Learning Software Engineering profile, and 3 consultant profiles. 

As evident by the placement highlights, ISI Kolkata is a great option for Data Science job roles. But if you are interested in job roles like Software Engineer then joining IISc or IIT will be better.

The course fee for M.Tech at NIT Calicut varies depending on several factors, such as the specialization you choose, your category (General/OBC/SC/ST), and the mode of admission (GATE/non-GATE).

For GATE-qualified candidates, the fee for M.Tech is generally around Rs. 70,000-80,000 per year for the General/OBC category and around Rs. 20,000-30,000 per year for SC/ST category.

For non-GATE candidates, the fee is generally higher, around Rs. 1,20,000-1,50,000 per year for the General/OBC category and around Rs. 70,000-80,000 per year for SC/ST category.

However, it is always advisable to check the official website of NIT Calicut or contact the institute directly for the latest and most accurate fee structure for M.Tech courses.

My brother pursued his MS in Chemical Engineering from IIT Madras back in 2016 and these are some of his experiences for the overall MS program offered at IIT Madras-

1. The MS program at IIT Madras is extremely fulfilling for students who want to pursue a career in research by going for a Ph.D. and Post Doc.
2. The MS program is different from the M.Tech program. The M.Tech program is highly coursework oriented and is a better choice for securing a job.
3. IIT Madras has, over the years, made efforts to give MS graduates an equal chance at placements.
4. MS students tend to focus a lot more on their thesis as compared to M.Tech students.
5. MS students are given an extra year to submit their thesis (2+1).
6. An MS student, by the time of placement, will have worked extensively on a scientific topic and published at least one article in a reputed journal, or his article will be under review.
7. This research work holds benefits during placements. The MS student’s CV is made impressive and data analysis and scientific reporting skills are highlighted. A little smart work will help you convince your interviewer of how these skills make you a suitable candidate for the offered position. 
8. Very few IITs offer an MS degree and many employers are unaware of this course.
9. The MS degree becomes demanding and tough because you need to get an article published in an international journal to obtain your degree. 

Though not specific to the Mechanical branch, I hope this information about the MS program at IIT Madras helped you gain important insights regarding the same.
