An initial recruiter conversation to review your background, motivation for the role, and fit for Datadog. The recruiter usually outlines the full interview loop, shares prep guidance, and confirms expectations around timing, level, and team alignment.
A coding-focused interview with an engineer, often on CoderPad or HackerRank, centered on data structures and algorithms at an easy-to-medium level. Some versions also include brief product-context questions or a short discussion of how you would use Datadog in practice.
Depending on the team, candidates may complete a HackerRank task or take-home assignment before or alongside two live coding interviews. The work often includes practical tasks like SQL, Bash, agent setup, log parsing, or tree traversal, with attention to clean implementation and clear explanation.
A full-length design discussion covering distributed systems, pipeline architecture, and scaling trade-offs such as fault tolerance, latency, and cost. Candidates are expected to reason through the problem space, explain decisions, and show how they would approach a real-world system rather than chase a perfect solution.
Later-stage conversations focus on a past project deep dive, behavioral judgment, and a hiring manager discussion. Expect detailed questions about your technical decisions, personal contributions, conflict handling, prioritization, and why you want Datadog or are leaving your current role.
