Networking is relationship building

No MBA ever needs to network

Through networking you increase your visibility, it’s an avenue to exchange ideas, learn about different industries, and create new job opportunities. It grows your self-confidence and improves your creative intellect; innovations are most times formed by external factors around where we find ourselves. The intellectual capability in different careers is significantly enhanced upon from interactions we have built with other persons over a while- Forbes
And while networking was easy at business school, afterward most of us go back to everyday life. Yes, you kept in contact with some classmates, maybe, but times things change and life happens. Eventually, you get into a position where you start to think that you got little to no value from your MBA, you forgot what you learned, and lose touch with your alum or classmates.
