How to write a cover letter
Individual European states may have different expectations on how to write and what to include in a cover letter.
There are, however, two main types of cover letters depending on whether you make an application with reference to a job advertisement or an unsolicited application. In the latter case you must explain how the company you apply for attracted your attention and why you would like to work for this company in particular.
Bear in mind that the point of your cover letter is to attract the company’s attention. You should therefore not only make sure that your cover letter has a clear layout and fulfills any formal criteria, but also give it a personal touch. Ask yourself why the company would choose to hire you from a pool of applicants with similar qualification! Explain your MOTIVATION to work for or make an internship at THIS PARTICULAR COMPANY and in THIS PARTICULAR AREA.
