Global staffing is an essential aspect of human resource management in multinational corporations (MNC) (Collings & Scullion, 2009). As the positioning of multinational organizations gradually becomes global, multinational companies must cultivate suitable global personnel. Flexible and adequate staffing and management skills can give transnational corporations a particular competitive advantage in global operations (Collings & Scullion, 2009). Understanding the background of the local market and gaining and sharing tacit knowledge in jobs around the world are all necessary professional skills for the multinational company (Harvey et al., 1999). However, human resources management departments also face more significant challenges as the multinational company expands its business globally. Learning how to effectively respond to the staffing problems of multinational companies in the course of operation reflects the company's operating capabilities. This article will first define and elaborate the global staffing policy, while the factors that will make the system more effective will be introduced. Secondly, the current problems and challenges faced by multinational companies will be listed, followed by corresponding measures. Finally, other recommendations will be provided in some areas for the human resources of multinational companies.
