Companies have to encourage them to study the language and cultures. Many employees taking on international assignments are unsuccessful because their families can not adjust to their new surroundings. Hence, it is necessary to organize training for the employee and his family before departure to help them adapt to the new environment. To choose the best employee for the job, management should emphasize cultural sensitivity; require previous international experience, and screen candidates' spouses and families (Treven, 2006). The company must consider both headquarters practices and those prevalent in the countries of its subsidiaries. When making a hiring decision, people in an achievement oriented country consider skills, knowledge, and talents. When selecting employees, the company should consider their culture, age, gender, and family background. Employees should be selected whose personal characteristics fit the job. An international human resource firm has to choose among training employees located in subsidiaries, training to prepare expatriates for assignments abroad, and development of a special group of globally minded managers. Hence, the expatriate can do his job competently, learn to live comfortably in a new culture, and ensure that his family adapt as well. International human resource firms develop training programs which may be carried out in two ways: centralized and decentralized. With a centralized approach, training originates at headquarters and corporate trainers travel to subsidiaries, often adapting to local situations. This fits the home country model. Trainers could be sent from various positions to any other location in the company. In a decentralized approach, training is on a local basis, following a host country model. When training is decentralized, the cultural backgrounds of the trainers and trainees are usually similar. Local people develop training materials and techniques for use in their own area. To maximize training effectiveness, it is important to consider how trainees learn most effectively. Global companies must have a group of managers with a global perspective. Companies must identify managers with global potential and provide them various training and development opportunities. As global managers have international assignments, working on cross-national teams and projects, and learning other languages and cultures contribute to making a manager more globally minded. In addition, global companies should include not only home country nationals but also host country nationals and third country nationals in this group (Treven, 2006). The most important aspect of expatriate training is cross cultural training. Such training prepares an expatriate to live and work in a different culture because coping with a new environment is much more challenging than dealing with a new job.
