What is a Bewerbung?
A Bewerbung is a German job application: a formal cover letter (Anschreiben) that introduces you to an employer, explains why you are a good fit for a specific role, and asks for an interview. It usually accompanies a CV and any supporting certificates.
German employers expect a specific structure and a formal, professional tone, so a well written Bewerbung is often what decides whether your application gets a second look.
