Opinions of trained professionals
« Les formations de G.A.C. Group m’ont permis de fiabiliser mes connaissances et de maîtriser les nouveautés comme la DSN de substitution. Je suis désormais beaucoup plus à l’aise sur la vérification de mes flux. Un accompagnement basé sur la fiabilisation et l’écoute. »
