Recrutainment stands for experience-oriented recruiting. It is an example of an English sounding word that does not exist in English. It was created by the Cyquest GmbH, a German company specializing in e-Assessment tools and Human Resources Advertising and Marketing solutions.
Casting originates in performing arts and refers to a process for selecting a cast of actors, dancers and other talent for a live or recorded performance. As neologism in German language, casting stands for selection of employees independent of an industry (Auswahlverfahren von Mitarbeitern) and is used internally to probably pay justice to one’s need of being cool and trendy. Fortunately, recruiters are still called Recruiters and not Casting Directors.
