Designing a self-serve experimentation platform
Source: interviewintermediate
WHAT IT TESTS: building safe experimentation as a platform, not a service. OUTLINE: SDK with sane defaults, automated pre-launch validation, sample-ratio and guardrail-metric checks.
WHAT IT TESTS: whether you can productize experimentation so non-experts ship safely without a growth engineer in the loop. ANSWER OUTLINE: an SDK abstracting assignment and exposure logging; pre-launch checks for mutually exclusive layers, traffic budgets, and metric wiring; runtime guardrails like sample-ratio-mismatch detection, auto-rollback on regression, and kill switches.
