This is a huge task and cannot be simply compiled in a line or two. I would suggest you let us know which college you may be interested in and we can help out with details. Please check the rankings here https://engineering.careers360.com/colleges/ranking/2017. You can know which college is good. As for placements, you should check each college page for their placements record. However please understand that the placement trends may only be available. You can also search reviews by students of those colleges so you have a better idea of how the actual situation is.
