Company profile
Datadog
Datadog provides the unified observability and security platform - metrics, logs, APM, RUM, and Cloud SIEM - used by a huge slice of engineering orgs. Interviews are notably high-bar on systems engineering and infra fundamentals, with multiple coding rounds, a deep system design, and limited tolerance for vague behavioral answers.
The Datadog interview process
Datadog sets a high bar on systems engineering and infrastructure fundamentals. Expect multiple coding rounds, a deep system design, and limited tolerance for vague behavioral answers. Design rounds reflect real observability problems, so concrete reasoning about scale and data volume helps.
