The most common way to apply is to send a typed letter and a CV. For unskilled occupations, the application procedure is usually verbal. In cases where the applicant is sent by the public employment services, a standard reference letter is issued - which has to be completed by the prospective employer, stating their final decision - and submitted to the labour office.
If you apply for a vacancy found on the EURES portal, mention the national reference number. Both electronic and written applications should include a covering letter, which should be no longer than one page, to the point and typed. This letter, addressed to the employer or the organisation advertising the post, should contain important data not included in the CV. It should always be signed.
