After doing some research online, I would say that all the courses at ISI Kolkata are amazing if you know which field you have to choose. Everything depends on your choice of the field as every field is distinct from one another.

Now, I would mention that for M.Tech CS & QROR, these are already well-established Programs and need no introduction. 

QROR:

• It’s a course based on subjects in applied statistics and business analytics.
• If you want to be in Business Analytics, it’s better than CS & Crypto.

CS:

• It has theoretical CS as well as Artificial Intelligence and Machine Learning Courses.
• This will give you ample opportunity to do a Ph.D. as well as jobs in Data science positions.
• If you like coding and discrete mathematics etc then this is a zone to play in.

Crypto:

• ISI has India’s best Crypto people.
• And this is the first year of M.Tech Crypto so there is not much data available.
• But if you are not good in Abstract algebra Number theory then say not to this course.
• Research opportunities after M.Tech Crypto will definitely be better than that of QROR or CS.

I hope this helps you in clearing how all the three courses are distinct from each other. Each has its different criteria and comfort. 

As it’s a new IIT, the Metallurgy department is still developing in IIT Bhubaneswar. But this department is equipped with state-of-art lab equipment. School of Minerals, Metallurgical and Materials Engineering (SMMME) in IIT Bhubaneswar has an excellent fusion of faculty members from diverse backgrounds of minerals, metals, and materials engineering. This school has signed a partnership with the Institute of Minerals and Materials Technology (CSIR-IMMT) at Bhubaneswar. There is also a student and faculty exchange program with Warwick Manufacturing Group (WMG) at Warwick University, UK, and Shanghai Jiao Tong University, China. Also, according to 2019 placement statistics, 68% of the total M.Tech batch was placed with core and other sectors with salary packages ranging from 10 – 16 lakh per annum.

According to the National Institutional Ranking Framework 2019, IIT BHU ranks at 14. The department of Metallurgy in IIT BHU is well equipped with lab instruments. Being an old IIT it also has great facilities and a large alumni base. Companies like Tata Steel, Tata motors, Saint Gobain, Flipkart, Oyo, Maruti Suzuki, etc visit the campus for placement of M.tech students.

IIT Bhubaneswar and IIT BHU, both the IITs are good choices for doing M.Tech in Metallurgy. So, pick one according to your convenience.

This totally depends upon your interest in the subject. You should give preference to the subject rather than a degree from college because your subject will shape your future.

The school of water resources is one of the pioneer centers for education and training in water quality and quantity management. There is an advanced research water quality lab in IIT Kharagpur. It is an old IIT and will provide more opportunities for higher studies in foreign universities, people also go to foreign universities from IIT Bhubaneswar but opportunities in IIT KGP will be more.

The water resources have limited scope considering the Indian employment scenario. If you are giving preference to the subject then join IIT Bhubaneswar. If your preference is not the subject then join IIT KGP because exposure and opportunities will be more in IIT KGP. A student planning for Ph.D. after M-tech will have much better scopes in IIT KGP than IIT Bhubaneswar.

The job profiles of Transportation Engineers include construction planning for bridges, highways, municipal utilities, drainage structures, traffic control devices roadway lights and intelligent transportation systems. Under Transportation Engineering, IIT-B covers key subjects like Urban Transportation Planning, Traffic Engineering Studies, Fundamentals of traffic flow theory, etc.

Public and Private transportation services are the major recruiters and the job profiles offered to transportation engineers are Systems Engineer, Transportation Innovation Analyst, Mechanical Quantity Survey and Bill Checking Engineer, Transportation Planner, Civil Transportation Designer,, and Infrastructure Utilities Engineer, Electrical Engineer, Senior Transportation Modeller.

In 2019, IIT-B recorded 89% placement for civil engineering students with top recruiting companies like L & T Construction, L & T Ltd., etc. The placements witnessed a high jump in 2019 as compared to 62% in 2018. The average package for civil engineering was 7.5 lakhs per annum in 2019. The number of companies conducting placement drives at IIT-B also showed a significant jump to 89 in 2019-20 compared to 55 in 2018-19.

The scope for transportation engineers in India is significant as with the developing economy, India is in need of advanced traffic networks, pavement constructions, smooth traffic flow structure and R&D consultants.
