Growth and Product Metrics Analysis Questions

Analysis skills specific to growth and product contexts: interpreting funnel metrics, cohort and retention analyses, attribution of acquisition versus activation, detecting seasonality and external event impacts, and diagnosing conversion or engagement changes. Candidates should be able to form hypotheses about what drove changes, propose targeted follow up analyses or A B tests, and identify which additional metrics are needed to evaluate unit economics and growth efficiency.

Three product experiments that overlap in time may interact and cause interference on the same KPI. Explain an analysis strategy to estimate the individual and combined effects, discuss statistical models or ANOVA approaches that could help, and describe practical mitigations to avoid confounded results in future experiments.

Design an experimentation platform and metrics pipeline that supports: randomized assignment, feature flags, metric computation (rolling aggregates and cohorts), and offline re-computation for 100M monthly users. Discuss components for event collection, storage, metric definitions, experiment assignment, monitoring, and how to ensure data quality and low-latency dashboards.

Explain the difference between retention reported by cohorts (e.g., percent of users active in week N) versus sticky metrics (e.g., median sessions per user). Describe scenarios where cohort retention can improve while overall engagement metrics decline and how you would investigate such contradictions.

Explain Type I and Type II errors in the context of A/B testing, why both matter for product decisions, and give a concrete example where misunderstanding them could lead to a bad business decision.

Describe how you would detect seasonality and external-event impacts (holidays, product launches, macro events) when evaluating weekly growth metrics. Include specific statistical or visualization techniques and how you would separate real product changes from seasonality.
