What Are the Key Performance Indicators (KPIs) for the First 90 Days?
Datadog measures SDE success through code contribution quality, collaboration metrics (e.g., positive code review feedback), and project impact. Judgment: Meeting KPIs is expected; exceeding them through innovation (e.g., proposing a new feature based on customer feedback) is what gets noticed. Timeline:
- Days 1-30: Onboarding and project setup
- Days 31-60: First production deployment expected
- Days 61-90: Contribution to a team-wide initiative
How to Navigate Datadog's Engineering Culture for Maximum Impact?
Lived Experience: A 2025 debrief highlighted an SDE who struggled due to not seeking early feedback. Insight: Datadog values proactive communication. Schedule weekly check-ins with your mentor and engineer peers for the first 60 days. Not X, but Y: It's not who you know, but who knows your work; present your project in at least two team meetings within the first 90 days.

- 40%: Project and onboarding tasks
- 30%: Tech stack deep dive
- 30%: Exploratory learning of adjacent systems
