  • Ils voient d’abord ce qu’ils ont demandé. L’expérience qui correspond à l’annonce passe en tête, avec les mots de l’annonce, pour qu’une lecture rapide la trouve en quelques secondes.
  • Il passe les logiciels de tri. Beaucoup de grands employeurs utilisent des logiciels qui classent les CV selon leur proximité avec l’annonce, souvent avant qu’une personne ne les lise.
  • Dans la langue de l’annonce. Une annonce en espagnol reçoit un CV en espagnol, même si le vôtre est en portugais.
  • Vos faits, rien d’inventé. Votre propre expérience, réordonnée et reformulée. Ce que l’annonce demande et que votre CV ne montre pas vous est listé, à ajouter seulement si c’est vrai. Vous le relisez avant de l’envoyer.
