Trainees are interns recruited through "Management Trainees". "Management trainee" is a very common phenomenon. Companies that pay attention to practical operation will arrange internships and training for students at different times and select outstanding people to enter the company. Students with solid professional foundation, excellent personal comprehensive quality and potential are favored by various companies. Although it is recruiting trainees, the conditions of multinational companies are still very harsh. In addition to the corresponding decline in professional skills and work experience, the investigation of students' professional background and personal quality is basically the same as that of formal staff recruitment. The recruitment process is similar to that of regular employees, and it needs to go through resume screening, written examination, multiple rounds of interviews and other processes.

Although multinational companies have invested a lot of energy in internship projects, students do not have to stay in the company after the internship. They believe that the internship program is not only to train talents for the company, but also out of a sense of social responsibility, providing a bridge for college graduates to move from school to society and helping them improve their employment competitiveness.
