For written applications, make sure that you create a complete file containing your application letter, CV, a photo and some letters of recommendation. Make sure that there are no spelling mistakes in any of your documents and that your file looks perfect.
The application letter should comprise not more than one page and the CV should be limited to two pages and include the job contents - or you can add a job profile with your skills and expertise. The folder style should be appropriate to the function.
If you send your application by e-mail, you are advised to send your covering letter, CV, photo and letters of recommendation all in one document.
