Hello,

It's delightful to know that you are eligible for both the esteemed colleges for a branch in-demand like ECE. IIIT Hyderabad is one of the best colleges of India for circuit related branches. The sheer location of IIIT Hyderabad makes it a better college for job prospects. The updated curriculum of IIIT Hyderabad makes it a better option for ECE branch than IIT BHU or IIT Guwahati Chemical. As per the Information, only 60% of eligible students in IIT Guwahati got placed and the average package was around 14 lac. While IIIT H offered 100% placements. So if you are studying engineering for Jobs you should be choosing IIIT H. Traditional IIT tag is very helpful in your early career and if you are dedicated enough you can slide branches in IIT-G. Thus, it's really your choice.

The reason why I am not even discussing IIT-BHU is that until you have a lot of interest in Mechanical, it stands a bit below IIT Guwahati or IIIT Hyderabad.

In my opinion, you should leave IIIT Hyderabad only for OLD 5 IITs(B, D, M, K, KGP).
