Avoid mistakes in the application
The most important part of the application is the resume. Make sure that the data is complete and that you have a professional photo. Attach all relevant certificates and confirmations of internships.
As a young professional, you probably do not have much work experience yet. Therefore, you are welcome to list personal hobbies and knowledge. You would like to enter the healthcare sector and have a trainer's license? You have studied mechanical engineering and work privately in a workshop? Do you enjoy learning foreign languages? For your employer, this is proof of real passion!
In the cover letter, you should also make it clear why you are interested in the job and, above all, in the company in particular. Show that you know what you want!
You are also welcome to include soft skills and other personal strengths in your cover letter. After all, your future boss wants to know what makes you stand out as a person. Remember, however, that you must be able to justify and prove your statements. Also, avoid generalities!
Very important: Have a second person read your application for spelling mistakes at the end. In many professions, correct German is very important.
