UPES

Government colleges have more reputation than private colleges. But if you are looking for good placement, then some government colleges don't provide good placements (not all of them).
And there is also mass recruitment in all colleges. So you have to be unique if you want a good package. UPES provides good placements. But mass recruitment is also present in UPES.
VM provided more than 15 LPA. Microsoft gave an offer of 11 LPA.

I don't know much about MAIT, Delhi but in UPES it is good. There are several sub branches for CS. It's up to you which branch you will choose. Placements in UPES is also good. Faculty is also experienced which will give you full support. The highest package offered was around 27 LPA. Top recruiters are Microsoft, VMware, dell, LNT, IBM.

According to me, Graphic Era is better, because in UPES, fees is very high and UPES is good for specialization course. For core courses GEU is better option and placements in GEU is better than DIT.

UPES is University of Petroleum and Engineering Studies. It has many branches under it:
School of Engineering
School of Computer Science
School of Law
School of Management
School of Design

The placement record is quite good and the college guarantees 80% placements.

It's one of the best colleges for petroleum engineering.
