Dear Kavita, Shiv Nadar University is better than JSS Noida at least when placements are considered.

If placements are considered, there is rarely any scope for placements especially for core branches in JSS Noida. Don't expect that product based companies will visit this campus. Average package will be around 3.3 lacs per annum or even lower but almost everyone will be placed. This college is very strict in case of attendance. If you are hoping to sometimes bunk your classes and enjoy your social life,  and your attendance goes down the required limit, your parents will be called and complained regarding your attendance as a middle school kid.  Even the faculties won't support you for attendance if you are missing classes because of their project work. You are only recommended to join this college if you have no other option left for you.

Coming to Shiv Nadar University, greater Noida. Though placements are little better here, but still not all are placed. It completely depends on one's individual efforts.  If you want to enjoy your social life, join here.  SNU has opportunities where you can increase your social circle. Taking UWEs and CCCs help you to interact with students from different branches, schools of study and also a different year. From the student's side, there are many clubs which hold events throughout the year which create a chance for social interaction. There is also an annual college fest BREEZE. Coming to hostel life here, it is one of the best part of this college with a descent food quality. There is also option of buying food from la carte and ordering from nearby Dhabas. Surprisingly many tv series sites are blocked here. Even its location is somewhat at the end of  civilisation, very far at a distant place.

Though if you have some other options left, then I won't suggest you to join any of them. But still if you have no other option left, then I would still suggest Shiv Nadar University.

I hope this helps you!
