The first year lays down the foundation for the entire program so you need to be very careful and smart in planning your routine. Make a note of the following tips that will help you if you are a first-year student at BIT Mesra.

• Ask beforehand if the bus will take the Bariatu route or the Kokar route for buses plying Ranchi at 1 PM.
• Maintain a healthy bond with seniors instead of being arrogant. They will genuinely help you in times of need. 
• Mechanical Engineering lab sessions are a good chance to showcase your drawing skills which might also fetch you good marks.
• Join the clubs that align with your interests and make the most out of them.
• Maintain a decent CGPA if you want the best companies to pick you.
• Don’t mug up the concepts while preparing for the exams rather try to grasp the concepts well,

Hope this will help you!

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. 

My friend has completed All-course MTech at IIT Hyderabad and claims that it has zero recognition outside IIT Hyderabad with a dearth of job opportunities. The course is a one-year program that does not require you to write a thesis/research. All you need to do is study courses in the classrooms. This is a very poor choice for those targeting a Ph.D. as this program isn’t known even at other IITs. 

You will be given alien treatment and will end up wasting Lakhs on a useless degree. The majority of the IIT Hyderabad community is unaware of this course. The curriculum is poorly designed and very rigid. The world is intense, sparing you no time for extracurriculars. The majority of the first batch left the course within a few days.

The course is a complete waste of money and time so I am strongly against anyone joining it.
