Should I go for nit Calicut eee or bits hyderabad ece??please provide details on both(median package and opportunities and scope)

Between NIT Calicut and BITS Hyderabad, the latter is the better option irrespective of the branch you are getting. Here are a few points of difference between the two institutes. 

• BITS Hyderabad EEE placements are great and students get placed in core electronics companies such as NVIDIA, National Instruments, Texas Instruments, MediaTek, etc while NIT Calicut has very few core companies and students are usually placed in IT companies.
• BITS Hyderabad charges very high fees whereas NIT Calicut charges average fees. 
• BITS Hyderabad offers a better exposure and research culture in comparison to NIT Calicut.
• BITS Hyderabad has an excellent faculty pool and the labs are equipped with modern instruments much better than NIT Calicut.

In my opinion, BITS Hyderabad should be your preference provided that you have no monetary issues.
