I'm not sure why people are so obsessed over networking. It's way overrated. People do MBAs to get a better job in their current line,and to propel themselves into management, or for a career switch into finance or ibanking. Networking rarely figures in the equation unless you're doing an EMBA. Look, how much have u gained from people u know in school, other than going for drinks and trading gossips?
The good bschools overseas - not sure about the local schools - can give you a big headstart in a new career, typically in big-name MNCs, the fortune 500s, the best employers.
Big corporates still prefer to groom talent with good MBAs. ROI is definitely good.
