Internationally operating companies utilize the deployment of their personnel to make the internal management of the corporation more efficient and to enhance the cohesion of the corporate group. Additionally, the challenges of international assignments are compounded by the fact that subsidiaries of corporations must operate in different national territories with various political systems and differentiated legislation. Therefore, corporations expect their employees to be proficient in the local language and often English as the corporate and group controlling language in order to succeed in the local branch. Furthermore, it is advisable to have knowledge and understanding of the history, economy, and culture of the respective country to better produce and sell the company's products and services. HR personnel must be adept in this context.
