In India, the job prospect of a CS graduate is more, compared to ME, owing to the presence of a large number of IT companies and their demand for mansource. So even if you don't make it to a tier-1 college, you will land a decent job, most preferably in an IT major/MNC. Though the salaries will differ a lot from that of tier-1 colleges.

On the other hand, there ain't a lot of core companies(for ME). So, even if you are not in an tier-1 college it won't matter. You have to be exceptionally good in your curriculum, score high and develop deep understanding of the subject. As most of the top core companies recruits through GATE.
