If a person receives a job opportunity through a friend of a friend rather than a direct connection, what underlying concept explains this phenomenon?

The phenomenon of getting a job opportunity through a friend of a friend relates to the concept of social networks and how connections work. In social networks, people are linked together, and these links can help spread information and opportunities. When you have a strong connection, like a friend, they can introduce you to their contacts, which expands your reach. For example, if your friend knows someone hiring for a job and tells them about you, that connection can lead to an opportunity you might not have found on your own. This shows how important relationships are in finding jobs and how connections can create pathways to new possibilities.
