The internship at an international company is a participatory one. You will get a real-life, business-related working experience at an international company.
You will go through the everyday working activities within a company, you will be involved in a network of people, learn to cope with working times and the pressure of deadlines. The placement contributes to the development of skills, knowledge and competences, enabling you to gradually grow in your future career.
Take for example an internship at the Marketing and Sales department of a large international fashion company in Düsseldorf, and look around their Finance department. Companies are very content to have pro-active, hands-on interns equipped with proper skills at their HR, Customer Support, Logistics or Marketing department.
