One of my friends is currently in his first year of M.tech CS at ISI Kolkata. Here are some crucial insights regarding the academics and placements according to his experience.

Academics: 

• If you have a CS background in your under graduation too, then all subjects in the first year will be mostly repetition for you. You can also check the exact list on the ISI website. However, many people with a CS background say that they have learned things in a much-refined way.
• In the second year, you finally get to choose subjects based on your interest which will help you in your final thesis.
• ISI is quite famous for cryptography but you can also find good thesis projects in prestigious fields like Machine learning, Image processing, Algorithms, VLSI, cognitive science, etc. Also, you get good guidance in all of these.

Placements:

ISI is particularly famous for statistics. So, most companies coming for placements offer Data science profiles. Very few companies would be offering developer job roles. So regarding the placements, it’s the best place to grab data scientist roles with lucrative packages. In the recent placement highlights, the average and highest CTC offered was 19.80 LPA and 42 LPA. 

Overall, ISI Kolkata is an amazing place to pursue your M.Tech in CS. The great academics and placement record indeed make it a haven for students associated with CS, mathematics, and statistics fields.

Since one of my cousins is currently a part of NIT Trichy, he can possibly elaborate on your question more thoroughly. 

• The dress code at NIT Trichy, as per my cousin, is very rare. 
• Unlike many other institutes in Tamil Nadu, the dress code at NIT Trichy is quite unflustered. 
• Students, mainly boys, cannot wear shorts into the class but can definitely wear t-shirts if they wish to. 
• The major drawbacks are rather faced by the girls of the institute because, at any seasonal point, they are mandated to wear salwar kameez or Kurtis. 
• It is both unjust and apparently not highly appreciated, in terms of climatic conditions, comfort zone, and other similar factors. 
• That said, it can get highly unmanageable during the summertime when the climatic conditions of Tamil Nadu usually soar the highest. 
• Trichy, Tamil Nadu, is extremely conservative in factors relating to the modern outlook of society. 
• Regardless of how much the campus has currently grown, there have been multiple incidents of fining bulky amounts to students for unconsciously flouting the dress code of the institute, even on basketball fields. 

However, it is best if you research more about the present scenario of NIT Trichy, regarding their dress codes, regulations, and other relevant aspects. 

Dr. Rahul Kala- assistant professor at the Department of Artificial Intelligence and Robotics is one of the faculty members at IIIT Allahabad. He indeed is one of the finest of all. Here are something you should know about him -

• Dr. Kala completed his 5-year integrated B.Tech (IT) and M.Tech (IT) program from IIIT Gwalior. 
• Dr. Kala also has a Ph.D. in Cybernetics which is from the School of Systems Engineering, University of Reading, UK. 
• Pattern Recognition and Classification, Intelligent Vehicles and Intelligent Transportation System, Robotic Motion Planning were areas he had done extensive research in. 
• There are a good number of books and research papers written by him. 

Naturewise, Dr. Kala is one fine person who is so very humble and simple in his ways. Unless he doesn't have any lectures or meetings to attend, Dr. Kala arrives at his office around 9:00-9:30 AM and departs right at 9:00 PM in the night. 

He can be described as someone who is-

• Down-to-earth 
• Known for his candor amongst both his students and colleagues
• Extremely passionate about what he does. He learns at once and makes decisions accordingly
• Would always be seen either going through certain research papers, AI Books, Thesis, etc., and scribbling some technical formulae on the whiteboard in his office which no student would be able to decipher and wonder why even did they opt for Robotics in the first place. 
• Even if you decide to barge into his office unannounced, he would never mind that and would be ready to help you with your thesis or coding.
• Even if it is a teacher or even a student, he would always be a great mentor to them 
• You'd always find Dr. Kala wearing a smile and would never find him cranky. He is someone who would also lighten the mood of the class by cracking a joke 

To capsule everything about Dr. Kala, the point that I've tried to make is that you'll receive the best guidance and learning from him. His company is always appreciated. Whether it is anyone from their labs or lecture rooms- they'd always praise having Dr. Kala around. 

It is a good college but the student should opt for it only when they are not getting into NIT and IIT. It is more reliable than most of the private colleges or universities as several companies are visiting every year and the placement rate of students is very good here. 

Below given are some facts about CGC (CEC) Landran:

• CGC Landran is good for placement only. 
• The college doesn't provide any practical or technical knowledge. 
• Faculties are good but the majority of the teachers only give assignments and yells at students for attendance and not submitting the assignment.
• One of the most important things that students need to be concerned about is to develop skills. Always try to be a skillful person and try to utilize as many resources as possible. Even a very good college scorer can't able to get placed in good companies because they lack appropriate skills.

The table shows a brief overview of the institution.

Overall, streams also matter if you are planning to take admission in CSE then it is the best otherwise you go for different options.
