The beauty of a connected, networked world is the ability to form relationships around the world at internet-speed. The global corporation wants to embrace social networks: the investment, both in money and time is small, and the potential rewards are high and quick. But organizations that do successfully implement a global candidate network strategy understand one crucial element- that it's not about them.
More specifically, the best global recruitment plan is built around the candidate. This is commonly understood in any domestic talent acquisition goals, but somehow forgotten when applied beyond your home country's borders. Understanding culture, language, laws, and practices are important, but just a start. Beginning a (work)life long relationship is the goal, and using social networks can help get you there.
