# Recrutement Challenge
## Introduction
Ce challenge a vocation à évaluer le niveau technique d'une personne souhaitant intégrer le BDOOC DATE DT COMCYBERGEND.
Ce challenge se décompose en 3 exercices.
- mise en forme de la donnée ;
- analyse et recherche dans la donnée ;
- visualisation de la donnée.
Les candidats doivent réaliser ce challenge et transmettre le code-source dans un délai de 7 jours.
## Population cible
### personnels civils catégorie A
Les candidats pour des postes de civil catégorie A devront réaliser ce challenge dans les langages de programmation employés au BDOOC :
- back-end : GOLANG ;
- front-end: SVELTE ;
- client : WAILS.
### personnels sous-officiers
Les militaires sous-officiers au BDOOC pourront réaliser ce challenge dans le langage de leur choix.
## Echange technique
Après avoir transmis le code-source, le candidat sera convoqué par le commandement du DATE pour réaliser un entretien technique. Cet échange permet de comprendre la manière dont le candidat a réalisé le challenge et d'identifier ses compétences et lacunes techniques.
