Software Engineer • Former Employee
Paris, France
October 27, 2025
Pros: Globalement, une expérience plutôt agréable chez Datadog.
L’ambiance est bonne, les collègues sont charmants et la rémunération est tout à fait convenable.
Cons: Mention spéciale pour les montagnes de friandises qui trônent dans les bureaux : un vrai paradis pour les gourmands. Et un enfer pour la ligne, si l’on ne sait pas se contenir, haha. En somme, un bel endroit pour travailler, à condition de garder le contrôle face aux douceurs.
