If the employer has activated anonymous applications for a position, you will be informed about this in the application process. The information will show at the top of the page once you have started your application.
Anonymous applications means that your name, nationality and disability (if applicable) will be hidden from the employer during the initial phase of the recruitment process. At a later stage in the process the employer will see the mentioned details.
It is the Ministry of Local Government and Modernization that is responsible for conducting experiments connected to anonymous recruitment in state-owned enterprises. The purpose of the experiment is to find out if anonymisation can work as a tool for integrating people with immigrant backgrounds into working life.
You fill out your CV and application as usual.
