J'ai postulé en personne. Le processus a pris 2 mois. J'ai passé un entretien chez Junta de Castilla y León (Valladolid) en mai 2011
Entretien
You need to study the material, since it's not quite an interview but rather a test you need to pass, so, you are fine if you have studied hard enough.
Questions d'entretien [1]
Question 1
Law regarding stuff and also about the European Commission, European Parliament and the rest of the European institutions
