Electrical and Electronics Engineering

Well most common software companies like Infy, Accenture come year on year but core placements are less comparatively and if you are interested in working in the core field you will have to get placed outside the campus and many of the previous year students have successfully joined core industry but it will require hard work.

eee is the best due to future job opportunities

there are plenty of job options both in government and private sectors.
and u can even go for further studies.

Samarth it would vary everytime. The variation would depend upon several factors. Therefore my advice would be to focus on name, size & recognition of the companies coming to VIT for campus placement.

Vit vellore is far better since it is more established one in terms of infrastructure academics placements and exposure

There can be some role for you in some machine design or in some electronic design but that would be very limited in a e-waste cycling industry

No its not possible . there is no correlation between EEE , ECE and environmental engineering

according to me there is difference in job opportunities between ece and tce, however the difference is small.if you are interested in tce then go for it . best of luck! !!!!
