A vacancy is more useful than a list of keywords. It tells you how one employer describes the occupation, what evidence matters to them and what remains unstated.
Mark three kinds of information
First, underline the daily tasks: customer contact, workshop work, documentation, stock handling or shift patterns. Second, mark explicit requirements such as school certificate, German level, driver’s licence or internship. Third, note qualities the employer asks you to demonstrate.
For each important point, identify honest evidence from school, work, volunteering, family responsibilities or a practical project. Evidence is stronger than repeating “reliable” or “motivated.”
Notice what is missing
The advertisement may not state vocational-school location, rotation between departments, working hours, required attachments or the contact person. These are reasonable subjects for a concise call or email.
Tailor the CV and letter to the occupation and employer, but never invent a skill. A clear gap can be addressed directly by showing how you are preparing.
