Vacancies are published in advertisements. An advertisement is an announcement of one or more vacancies published in a recruitment instrument with the aim of recruiting suitable candidates.

In Recruitment, recruitment instruments are implemented to cover workforce requirements. The type of recruitment and recruitment method used are depicted in the recruitment instrument (e.g. advertisements in print media, personal contacts through headhunting, or using the services of the local employment office or a recruitment agency).

Recruitment instruments are further classified by medium (for example, press, employment office, recruitment agency).

An advertisement is characterized by the following:

• Eight-digit number (for example, 00000020)
• Recruitment instrument and Medium
• Publication date and costs
• Advertisement text, if applicable
• Vacancies published in the advertisement
