I am from Mumbai, I have 3-4 friends doing Btech and 1 friend doing Mtech in VJTI.
Heres what I could get to know.
The faculty isnot good there. Infact sometimes whole semester passes by without a proper faculty for a subject. So, if you are depending on profs to learn, then its a big NO..
The placement is just above average, you can get good offers, if you are a good student. but, again companies prefer Btech students in comparison to Mtech ones.
Overall, campus life is good enough.
