Challenges Faced in Training Expatriate Managers

The training to the expatriate shall be conducted both before leaving the home country and after arrival in the host country. Both hard skills and soft skills training shall be conducted before the assignee leaving the home country. The hard skills are technical areas that are specific to the assignee’s job.
