Galgotias University

Galgotia College would be the best choice in terms of placement.

It's a good college with decent placements, for details check link :

To know the exact scenario for faculty and placements get in touch with the current students through social media or in person.

Dear Fahad,
If you first want to do diploma in engineering, try in good government polytechnics in Delhi like JMI polytechnic, Pusa polytechnic, Ambedkar Polytechnic. After then, you can try for B.tech with a option of lateral entry.
Galgotia University is good for B.Tech but don't compare it with MBBS, don't compare medical colleges with B.tech colleges.
I am also giving you a list of good B.tech colleges in Delhi.
Hope it helps you.

Yes Aditi Mahavidyalya is a good option however it is not in main campus.

Galgotias Noida is definitely better in terms of placements and faculty
