J'ai postulé en personne. Le processus a pris 1 jour. J'ai passé un entretien chez NATO (Luxembourg) en sept. 2017
Entretien
oral and written exams took a day long. The oral exam took roughly 2 hours in the morning including the time passed in the waiting room. In the afternoon I was passed through a written exam for around 3 hours. The exam was extensive and diverse.
