Which engineering will be best to do job after 4 years in terms of scope and salary?
If you want a Salary oriented or Money Oriented Branch then i would suggest you to go for Computer Science or Information Technology.
IT Sector is booming and in the near future all other aspects like Artificial Intelligence, augmented reality etc. will be on the peak.
If you want even more salary then you can opt for MBA from Tier 1 college.
