The ECE branches of all the three NITs you mentioned namely NIT Kurukshetra, NIT Hamirpur, and NIT Durgapur in terms of campus life, job opportunities, and curriculum. However, it's very important to make the most out of the branch you are opting for irrespective of the institute you choose. 

Follow the tips below to ensure you avail maximum opportunities as an ECE student

• Start focusing on programming if you want CSE in the first place because you will be appearing for IT companies. They will evaluate you on the basis of your skills so start working on them.
• If you are particularly interested in ECE, then joining any of these NITs will offer similar opportunities. Core jobs are usually less so you will have to study core subjects diligently and try to develop strong concepts. Work on projects and add value to your resume so that you can go for off-campus placements too.

Here is a brief companion of the placement statistics of the 3 branches

Ultimately, it depends on you what you want from your UG degree and now how good your college is.  

My brother is a B.Tech IT student at BIT Mesra. Here is a list of what you can expect from this 4 year course at BIT Mesra-

1. The CSE and IT batches have different sections.
2. If you work hard and prepare well, you can intern at companies like Gsechs , Amazon, Directi, Microsoft, etc. during your third year, through on campus internship drives.
3. IT students get the opportunity to be placed in top IT firms like Amazon, Flipkart, Microsoft, Snapdeal, among others.
4. IT is the best and the most chill branch of BIT Mesra.
5. You will have ample time for research work and projects.
6. If you work hard, you can achieve a good CGPA as an IT student at BIT Mesra.
7. DC, a software which offers 13 Mbps download speed, is a great bonus while you are at the BIT campus.
8. However, fees at BIT Mesra are a lot higher than the NITs.

Thus, if the fee is not an issue for you, I would recommend you to join BIT Mesra for your B.Tech IT degree.

IIEST Shibpur is better for CSE. It offers better academics, and facilities. IIEST receives more funding than NIT Durgapur. It has a better peer group as well, which is clearly reflected on the cutoff. 

The placement rate for CSE is around 80%. Students receive an average CTC of around INR 10 LPA. The highest CTC offered goes up to INR 39 LPA. Microsoft Media, Deutsch Bank, Mentor Graphics, Well Fargo’s, etc. are among the major recruiters that take place in the placement drive. 

NIT Calicut is the better possibility because of its efficient academics, infrastructure, and placement backing. Let us have a brief look at both institutes.

EEE at NIT Calicut

• Electrical Engineering is one of the most demanding courses, which opens up an eccentric career, especially for the zealous and hardworking ones
• Broad avenues for an electrical undergraduate include competitive exams like GATE, ESE, Defense Engineering Services, etc.
• NITC has an exuberant competitive culture as it follows the prospectus and pattern of IIT Madras. This ensures a healthier learning environment for the students.

ECE at NIT Durgapur

• Most of the students got settled as coders in the IT sector without any specialized knowledge about coding.
• NIT DGP ensures good infrastructure, academics, and placement for the students, just like other NITs

In defiance of this, the top students opt for EEE at NITs over ECE. So, you can go with the choice of EEE at NIT for an upright career

The choice of an institute depends on 2 major factors, the credibility of the institute and the branch you are getting. In terms of the worth of the institute NIT Rourkela clearly overpowers NIT Durgapur. NIT Rourkela ranks second in East India after IIT Kharagpur. 

NIT Rourkela Biotechnology is designed for students whose primary focus is pursuing qualitative research and g for a Masters's or Ph.D. That being said, it has limited job opportunities and the placement percentage is as low as 60%. Moreover, only a handful of core companies make offers and the average CTC offered is in the range of 5 -6 Lakhs. 

 NIT Durgapur Chemical Engineering is a suitable choice if you prioritize placements to research work. Even the core placements are decent here with companies like IOCL, etc visiting the campus during placements. 

Ultimately, both institutes and branches offer diverse opportunities so you need to consider your inclinations first. If you are a research enthusiast, NIT Rourkela Biotechnology is great but if your first preference is earning money, then go for NIT Durgapur Chemical Engineering.
