About the Company

Les Colettes sont un groupement de chasseurs de têtes indépendants. Le projet est né de la conviction que le recrutement dépend avant tout de l’énergie déployée pour accompagner entreprises et candidats (et vice & versa) et de transformer l’essai pour leur créer un avenir commun ! L’engagement du consultant et son optimisme sont déterminants pour que cette alchimie fonctionne. C’est pourquoi, les Colettes sont persuadé(e)s que pour garantir l’enthousiasme et la motivation de chacun, les consultants doivent rester eux-mêmes et devenir une entreprise dans l’entreprise ! Chaque Colette est donc une entrepreneuse ou un entrepreneur ! Convainquant, non ?
