There is so much that the employer you are applying to should know about you. What is the best way to convey all these details? It's simple: you create overviews.
These can be bullet points in the cover letter, an overview of your skills and competences and also a reference overview.
Please only include things that are relevant to your job and do not duplicate them. For example, no employer wants to read in every part of your application that you are a team player!
