Simply paraphrasing the CV in the covering letter is a frequent mistake. The purpose of the covering letter is to demonstrate your personal brand, explain why you are the right person for the job and differentiate yourself from the other applicants. You should explain how you can meet the requirements of the job. Write what skills you can bring and give examples of how you successfully applied these skills - for example that you created a 40-page publication for a DAX30 client within 48 hours which was printed in 28 countries. You should also include your soft skills and provide practical examples. An important point: You want to showcase your expertise and demonstrate that you could bring more value to the company than the average applicant. The covering letter should not be longer than one page.
