Sample interview questions
I would establish a metric hierarchy that includes relevance and engagement alongside retention, contribution quality, creator or community distribution, negative-feedback signals, and safety indicators. I would use guardrails and long-term experiments to ensure local ranking gains do not harm ecosystem health.
I would combine contextual features, content and community embeddings, geographic or language signals where appropriate, popularity adjusted for quality, and exploration mechanisms. I would measure performance separately for low-signal cohorts and progressively personalize as reliable behavioral signals emerge.
I translate company outcomes into clear problem statements, identify the highest-leverage bets and dependencies, and define measurable milestones. I communicate trade-offs early, keep the roadmap adaptable to experiment results, and give team members ownership of well-scoped technical decisions.
I would require offline evaluation, cohort analysis, bias and safety reviews, staged rollout, online guardrail metrics, rollback plans, and ongoing monitoring for drift. I would also partner with policy and safety teams to assess predictable effects on vulnerable communities and content distribution.
I would quantify expected user and business impact, clarify latency, reliability, and cost requirements, and compare incremental and platform-level options. A joint roadmap with shared milestones, ownership, and success criteria helps ensure infrastructure work supports durable product outcomes.
