Please don’t forget to include your salary expectations and earliest starting date and/or current term of notice.


Make sure there are no gaps in your education and work record. You should generally begin with your higher education details. Any gaps (e.g. application phase, stays abroad, etc.) must be explained. We are also interested in your language and IT skills, as well as any hobbies.


Please attach all important documents. These include employer references, school leaving, training, and higher education certificates. However, seminar certificates or similar participation documents, often just make your application unnecessarily bulky.
