The truth is almost all the private institutes are the same.
It totally depends on you which college you prefer taking into account the fees (it’ huge) and the distance from your home(trust me it matters).
Placements are good at KIIT but the crowd is huge , you will get placed somewhere for sure but the package won’t be big.Only few excellent students bag packages above 10lakhs per annum.
I don’t have much idea about Symboisis,Pune. Rest is upto you.
All the best!
