However, this is a popular trend, and you don't have to follow it. It is best to make a decision based on your own individual preferences.
First, you should make up your mind regarding the domain you want to continue with.
Here are some information to make your decision easier:-
Comparing the different IITs and their branches is a complex task, as there are various factors to consider.
Firstly, in terms of college life, both IIT BHU and IIT Mandi have their unique characteristics. IIT BHU has a rich history, with a large and diverse student population, while IIT Mandi is known for its serene location and a close-knit community of students. The campus life of both these institutes is quite active, with various clubs and societies organizing events and activities throughout the year. However, the experience of college life is subjective, and it ultimately depends on an individual's preferences.
Regarding placements, both mechanical and electrical engineering are considered core branches, and hence, have good placement opportunities in their respective fields. IIT BHU has a well-established reputation in the field of mechanical engineering, with several companies recruiting students for internships and full-time roles. Similarly, IIT Mandi has seen significant growth in its electrical engineering department, with several reputed companies such as Microsoft, Amazon, and Texas Instruments recruiting students.
IIT Roorkee is another top-ranked institute, known for its excellent civil engineering department. Civil engineering is also a core branch and has decent placement opportunities in the industry. However, compared to mechanical and electrical engineering, civil engineering is considered to have relatively fewer job opportunities in the private sector. Nonetheless, IIT Roorkee has a good track record of placing students in reputed government organizations such as CPWD, NBCC, and DMRC.
Both IIT BHU Mechanical and IIT Mandi Electrical have excellent placement opportunities and active campus life. However, choosing between the two ultimately depends on an individual's interest and preference. Similarly, while IIT Roorkee Civil has good placement opportunities in the government sector, it may not have as many options in the private sector compared to the other two branches.
IIT Roorkee Civil Engineering is arguably the best in Asia. It has an impressive placement record for the Civil branch. According to the recent placement highlights the average CTC offered at the institute is 10 LPA. The brand value of IIT Roorkee has its advantages.
BHU Mechanical department is considered to be notorious due to the presence of strict professors but at the same time, you will get a lot of opportunities to learn loads of stuff and also would get a very vibrant campus culture for your college life. The average CTC offered at BHU is 8 LPA.
If you have inclinations towards the Electrical Engineering domain of engineering then you can go for Ropar. The only disadvantage for the institute is that many companies which offer recruitment opportunities at the Top 7–8 IITs do not offer any such recruitment opportunities in Ropar.
I have friends at these institutes, and based on what I heard from them I will say keep Civil Engineering at IIT Roorkee as your first preference.
