never go by rankings!!!! theres politics involved in that too! all these private institutions pay up these ranking agencies to present a good rank in front of the nation thru the magazines and create hype and interest in their institutes! why do u think all private institutes havea very high application fees and for those who get thru, a very high fee for studies....heres where they spend money...ADVERTISEMENT! as is a well known fact, govt engg colleges have a very low fee for education and appication procedure...so most students who qualify go there....thus the creamy layer(read:good applicants) favor them...the rest go to private colleges. All companies who are interested in campus placements, thus, only go to (or prefer) govt engg colleges....because they cant compromise on quality...then they go to private engg collges but their decision is entirely based upon the candidates performance in any engg college they go to and they never decide on which colleges to go to.
