      Software Engineer II Interview

      21 Jul 2025
      Anonymous employee
      Paris
      Accepted offer
      Positive experience
      Average interview

      Application

      I applied online. The process took 2 months. I interviewed at Datadog (Paris) in Jun 2025

      Interview

      I truly can’t emphasize enough what an incredible experience I had throughout the entire interview process at Datadog. From the very beginning, the recruiter was transparent, encouraging, and incredibly supportive — consistently sharing helpful resources, tips, and timely feedback that helped me feel confident and prepared at every stage. The process itself was well-structured and thoughtful. It started with a recruiter call, followed by a technical/coding interview — and I really appreciated receiving feedback from my recruiter right after. Then came the face-to-face round, which included four sessions: one coding exercise, one system design interview, a deep-dive into a past project, and a values-based conversation where you're invited to reflect on key moments and decisions in your career. What stood out most was how human and respectful the entire experience felt. I always felt comfortable, heard, and genuinely excited about the opportunity. I also appreciated how much I learned about the company, the team, and the role throughout each step. A special shoutout to my recruiter, who went above and beyond — with regular check-ins and continuous support, they truly made the process smooth, motivating, and enjoyable. I couldn’t be happier with the outcome!

      I really appreciated the care from the recruiting team during this interview process. The recruiter made sure to check in at each step and provide feedback (which is rare to receive in this industry). I was also very impressed by the kindness of all of my interviewers and their willingness to answer all of my questions.

      Difficult interview

      Application

      I applied through a recruiter. I interviewed at Datadog in Jun 2025

      Interview

      Le premier entretien RH se focalise sur l'experience, les motivations, le fit avec l'offre. S'en suivent deux entretiens de coding (test d'algorithmique style leetcode). Suite à ça, un entretien de system design, dont l'objectif est de tester les capacités à concevoir l'architecture technique pour répondre à un problème vague donné en début d'entretien. Puis enfin un entretien sur l'expériences et les valeurs (discussion technique sur un projet + questions comportementales). Le process est clair, le talent acquisition manager m'a donné des conseils tout au long du process pour bien préparer les entretiens.

      Donner un exemple de situation complexe qui vous sont déjà arrivées durant votre carrière, et comment vous avez réagi / ce que vous en avez retiré ?
