Placement:

The placement details at the institutes are as follows.

All the IITs are of high repute and globally recognized. IIT BHU takes the upper hand when it comes to chemical engineering, which is depicted from their quality research. However, you should choose the institute according to your convenience.

IIT BHU CSE is better than IIT Patna CSE due to many reasons. First of all, the coding culture at IIT BHU is unparalleled. Although the coding culture at IIT Patna is quite revered, it still does not match IIT BHU. The institute(IIT BHU) also conducts Tech fests(Codefest being a prominent fest). Codefest has been successful in creating a competitive milieu for coding by inviting students from all over the world. The seniors at IIT BHU are very helpful and provides guidance. 
An underpinning feature of IIT BHU is the Internship opportunities that it provides for students. The overall infrastructure of IIT BHU is also better than IIT Patna. While NIRF rankings(2019) rank IIT Patna at an overall rank of 22, IIT BHU is ranked at 11. The overall placement performance and scenario of IIT BHU also better when compared to IIT Patna. In 2019 a total of 66 students were placed with average packages ranging from 10 LPA to 58.21 LPA from CSE in IIT BHU. However, the 2019 placement highlights of IIT Patna revels 50 students from CSE got a placement with an average package of 13.5 LPA.
IIT BHU also has a vast number of alumni as compared to IIT Patna. Many alumni from IIT BHU CS have secured high echelons in eminent MNCs and PSUs. While some have placed themselves in reputed companies or opted for startups, others pursued further studies in reputed universities of the world. However, considering all the factors, CS at IIT BHU is definitely a better choice as compared to CS at IIT Patna. 

Before the commencement of the session 2017, internet used to be a limited resource for IIT(BHU). IIT Bhubaneswar used to be the Institute of Technology ( IT BHU), whose administration fall under Banaras Hindu university but it got a different stature in converting into IIT in 2012. Although, some facilities like Internet services were still under BHU administration for long.

So before 2017, there were limits on the internet usage of 4 GB and which could be accessed through LAN only and which this question asks about. But after it, IIT BHU gets its own wifi services and there is no cap on usage. Hence you can use as much data as you want once availing internet connection of college. So anyone today can surf more than 4GB in IIT BHU.

M.Tech in Electrical Engineering programs offered by IIT BHU and IIT Bhubaneswar are not similar, so the choice must be based on what you are looking for in the program. The EE department of IIT BHU offers M.Tech programs in Electrical Machines and Drives, Power Systems, Control Systems, Power Electronics, and Interdisciplinary Systems Engineering. Whereas Electrical science department of IIT Bhubaneswar offers an M.Tech program in Power system engineering, and Electronics & Communication Engineering.

IIT BHU has one of the largest and well-connected alumni foundation in India. The placement scenario of EE is very good at IIT BHU. According to 2019 placement statistics, a total of 52 companies visited the campus for recruitment. 88 students got placed from the Electrical Engineering department with an average package of 8.19 LPA. On the other hand, about 68% of the M.Tech batch have been placed successfully in the year 2019 from IIT Bhubaneswar. A total of 89 companies visited the campus. The highest number of jobs has been received from core industries. The average placement package offered at this IIT was 11.44 LPA.

Apart from placements both colleges provide a large platform for research and development. There are 7 core laboratories such as Control system, Electrical machines & drives, High voltage, Network, Power Electronics, Power system, and System simulation in IIT BHU. Whereas there are 4 core laboratories such as Electrical Machines and Power Electronics, Power energy system, and Measurement & Electronic instrumentation present in IIT Bhubaneswar for research and practicals.
