Datadog Software Engineer II interview questions

The interview process was structured and enjoyable, consisting of the following stages: Recruiter introductory meeting, Live coding with a leetcode style exercise, Live coding in React, System design interview, Experience-based interview, Values and culture-fit interview, Team matching. What stood out to me was how conversational and collaborative the technical interviews were. In both the coding and design rounds, it wasn’t just about arriving at a "correct" solution, it felt more like a dialogue. I was encouraged to explain my thought process, and whenever I hit a roadblock, the interviewers were supportive and happy to help unblock me, which made the sessions feel more like problem-solving together rather than a test. The experience interview was also very engaging, it focused on past projects, technical decisions I made proactively, and offered space to reflect on architectural trade-offs and alternative approaches. Overall, the process was respectful, thoughtfully structured, and gave me a strong sense of the company’s collaborative culture.
