1. Q1

   Choose primary and guardrail metrics for a WhatsApp Business experiment aimed at improving meaningful social interaction rate. What metrics would prevent a harmful launch?

   MediumStatistics & Experimentation RoundA/B TestingMeta-specific

   Context: Include user experience, partner health, revenue, reliability, and long-term retention considerations.

   How to answer: A strong candidate would identify 'meaningful social interaction rate' as the primary metric, defining it concretely (e.g., messages exchanged in a 1:1 or group chat, excluding automated replies or short, transactional messages). For guardrail metrics, they would propose 'message send rate' (overall volume), 'user retention' (D1, D7, D28), and 'block/report rate'. These guardrails ensure the experiment doesn't inadvertently increase spam, reduce overall engagement, or lead to negative user experiences.

2. Q2

   During a Marketplace experiment, the treatment/control split is 52/48 instead of 50/50. How would you diagnose sample ratio mismatch?

   MediumStatistics & Experimentation RoundA/B TestingMeta-specific

   Context: Assume assignment logs, exposure logs, and eligibility filters may disagree.

   How to answer: A strong candidate would first confirm the SRM by checking the actual user counts in treatment and control groups against the expected split, and then perform a chi-squared test for statistical significance. To diagnose, they would investigate the randomization logic for potential bugs, such as incorrect bucket assignment or user ID hashing issues. They would also check for instrumentation errors, like data logging discrepancies or delayed event processing, and examine user eligibility criteria or pre-experiment filters that might inadvertently bias one group.

3. Q3

   Design a geo or country-level experiment for WhatsApp Business. When is this better than user-level randomization, and what are the analytical downsides?

   MediumStatistics & Experimentation RoundA/B TestingMeta-specific

   Context: Use matched markets, pre-period balancing, spillover checks, and fewer experimental units.

   How to answer: A geo-level experiment for WhatsApp Business involves randomizing entire countries or regions to either a treatment or control group, rather than individual businesses or users. This approach is superior when there are strong network effects, spillover effects between users in the same geography, or when the feature inherently requires a country-wide rollout (e.g., regulatory changes, payment integrations). However, it significantly reduces statistical power due to fewer experimental units, making it harder to detect small effects and increasing the risk of imbalance across groups due to confounding variables. Analytical downsides include increased variance, longer experiment durations, and challenges in causal inference due to potential unobserved differences between geo units.

4. Q4

   Two overlapping experiments on Instagram Reels both affect ad CTR and revenue per user. How would you detect and manage interaction effects?

   HardStatistics & Experimentation RoundA/B TestingMeta-specific

   Context: Discuss experiment registry, factorial design, exclusion rules, and interaction terms.

   How to answer: A strong candidate would first emphasize the importance of pre-experiment design to minimize overlap, but acknowledge it's not always possible. They would then discuss detection methods like subgroup analysis (users in both experiments vs. only one), interaction terms in regression models, and comparing observed vs. expected combined effects. For management, they would propose strategies such as sequential rollout, re-randomization, or using a robust causal inference framework like CUPED or switchback experiments if applicable, ultimately prioritizing user experience and revenue.

5. Q5

   Fraud, abuse, or policy gaming is suspected in Facebook Feed. Size the financial impact and propose an analytics approach to reduce it

   HardProduct Analytics & Business CaseBusiness CasesMeta-specific

   Context: Balance loss prevention with false positives and user/partner experience.

   How to answer: A strong candidate would first define the scope of 'fraud, abuse, or policy gaming' within Facebook Feed, identifying potential user behaviors (e.g., fake engagement, spam, coordinated inauthentic behavior). They would then propose a multi-faceted approach to sizing the financial impact, including direct costs (e.g., moderation, infrastructure) and indirect costs (e.g., advertiser churn, brand damage, user disengagement), using metrics like user reports, content removal rates, and ad revenue per user. For the analytics approach, they would suggest a combination of anomaly detection (e.g., sudden spikes in specific content types or user actions), network analysis to identify coordinated groups, and machine learning models trained on labeled data to predict and prevent future instances. Finally, they would emphasize A/B testing proposed solutions and continuous monitoring of key performance indicators.

6. Q6

   Inventory, capacity, or availability constraints limit WhatsApp Business. How would you prioritize scarce supply across customers, regions, or categories?

   HardProduct Analytics & Business CaseBusiness CasesMeta-specific

   Context: Use margin, fairness, service-level promises, strategic segments, and long-term retention.

   How to answer: A strong answer would propose a multi-faceted prioritization framework, starting with defining clear business objectives (e.g., revenue maximization, strategic growth, user engagement). It would then identify key prioritization criteria such as customer lifetime value, strategic market importance, potential for virality/network effects, and existing contractual obligations. The candidate should suggest a quantitative or qualitative scoring model to weigh these criteria and discuss mechanisms for dynamic adjustment based on real-time data and strategic shifts. Finally, they should touch upon communication strategies for managing customer expectations.

7. Q7

   Meta wants to launch or expand an ads/merchant monetization product related to Stories. What business metrics decide whether it is worth scaling?

   HardProduct Analytics & Business CaseBusiness CasesMeta-specific

   Context: Balance advertiser/partner value, customer experience, organic conversion, and incremental profit.

   How to answer: A strong candidate would first identify the core objective: maximizing revenue while maintaining user experience and engagement. Key metrics fall into three categories: revenue generation (e.g., Average Revenue Per User/Story, Conversion Rate of ads, Total Ad Spend), user experience/engagement (e.g., Story View Completion Rate, Ad Recall, User Sentiment, Opt-out Rates), and operational efficiency (e.g., Ad Load, Cost Per Acquisition for merchants, ROI). The decision to scale would depend on a positive trend in revenue metrics, stable or improving user engagement, and a healthy return on investment, often compared against a baseline or alternative monetization strategies.

8. Q8

   You need to create a self-serve dashboard for WhatsApp Business that PMs and business teams will use weekly. How do you define metrics and prevent misuse?

   EasyDashboarding, Stakeholder & Hiring Manager RoundDashboardingMeta-specific

   Context: Include metric glossary, data freshness, filters, caveats, and examples.

   How to answer: To define metrics, I would start by understanding the key business objectives for WhatsApp Business (e.g., user acquisition, engagement, monetization) and then identify specific, measurable KPIs that directly track progress towards these goals. This involves collaborating with PMs and business teams to ensure alignment and define clear metric definitions (numerator, denominator, aggregation, filters). To prevent misuse, I would implement robust documentation for each metric within the dashboard, including its definition, calculation logic, data sources, and known limitations. Additionally, I would provide in-dashboard guidance, tooltips, and potentially offer training sessions to ensure users understand how to interpret and apply the data correctly, and implement data governance to ensure data quality and consistency.

9. Q9

   Set alert thresholds for meaningful social interaction rate, ad CTR and revenue per user, and feed load time in Ads Manager. How would you distinguish noise from a real incident?

   MediumDashboarding, Stakeholder & Hiring Manager RoundDashboardingMeta-specific

   Context: Use seasonality, baselines, statistical thresholds, and business severity.

   How to answer: A strong candidate would propose setting thresholds based on statistical methods like standard deviations or control limits (e.g., 2-3 standard deviations from a moving average or historical baseline) for each metric. They would emphasize the importance of considering business context and impact, not just statistical significance, for 'meaningful' alerts. To distinguish noise, they would suggest correlating multiple metrics (e.g., a drop in CTR coinciding with an increase in feed load time), analyzing trends over time rather than single data points, and segmenting data (e.g., by region, device) to localize the issue. Finally, they would mention A/B testing results or recent deployments as potential causes for expected shifts.

10. Q10

    How would you audit a dashboard for Instagram Reels after stakeholders report that numbers do not match finance or operations reports?

    MediumDashboarding, Stakeholder & Hiring Manager RoundDashboardingMeta-specific

    Context: Trace metric definitions, source tables, filters, timezones, freshness, and access rules.

    How to answer: Start by clarifying the specific discrepancies and the reports in question (finance/operations). Then, systematically review the dashboard's data sources, ensuring they are correctly linked and refreshed. Validate the metrics' definitions and calculations on the dashboard against the official definitions used by finance/operations, paying close attention to filters, timeframes, and aggregation methods. Finally, trace the data lineage from raw data to the dashboard to identify any transformation errors or data loss.

11. Q11

    Define a north-star metric for Meta's Facebook Feed. What input metrics and guardrails would you track to ensure it is not gamed?

    EasyProduct Analytics & Business CaseProduct AnalyticsMeta-specific

    Context: Context: balance engagement, creator health, and advertiser value.

    How to answer: A strong north-star metric for Facebook Feed is Daily Active Users (DAU) who view at least 3 posts. This metric directly reflects user engagement and content consumption, which drives Meta's core business. Input metrics would include 'number of unique posts viewed per user', 'time spent scrolling', and 'number of reactions/comments'. Guardrail metrics are crucial to prevent gaming, such as 'post hide rate', 'unfriend/unfollow rate', and 'reported content rate', ensuring the quality and relevance of the feed experience.

12. Q12

    A new Marketplace feature has 30% adoption but no movement in meaningful social interaction rate. What analyses would you run before calling it unsuccessful?

    EasyProduct Analytics & Business CaseProduct AnalyticsMeta-specific

    Context: Consider exposure, eligibility, frequency, quality of adoption, and segment fit.

    How to answer: First, I would segment the 30% adopters to understand their characteristics (e.g., demographics, prior activity) and usage patterns within the new feature. Next, I'd analyze feature-specific engagement metrics, looking beyond overall social interaction rate to see if the feature is driving any new, albeit niche, interactions or if it's replacing existing ones. I would also investigate the user journey, identifying drop-off points and potential usability issues. Finally, I'd consider A/B test results (if applicable) and qualitative feedback to understand user intent and satisfaction with the feature.

13. Q13

    How would you segment users for Stories to find growth opportunities? Name segments, metrics, and potential actions

    MediumProduct Analytics & Business CaseProduct AnalyticsMeta-specific

    Context: Use behavioral, value, lifecycle, and acquisition dimensions.

    How to answer: To segment users for Stories growth, I'd start with behavioral segments like 'New Users' (first 7 days), 'Active Viewers' (viewed >3 stories/day), 'Active Creators' (posted >1 story/week), and 'Lapsed Users' (no story activity in 30 days). Key metrics for these segments would include Story View Rate, Story Creation Rate, Retention (D1, D7, D30), and Time Spent on Stories. Potential actions include onboarding flows for new users, creator tools/prompts for active viewers, and re-engagement campaigns for lapsed users, all aimed at increasing engagement and retention within their respective segments.

14. Q14

    Evaluate search or discovery quality for Instagram Reels. Which metrics would tell you whether users are finding what they want?

    MediumProduct Analytics & Business CaseProduct AnalyticsMeta-specific

    Context: Include query refinement, zero results, click depth, conversion, and long-term satisfaction.

    How to answer: A strong answer would start by defining search/discovery quality in terms of user satisfaction and efficiency in finding desired content. Key metrics would include engagement with discovered Reels (e.g., watch time, likes, shares, saves), indicating content relevance. Conversion metrics like 'click-through-rate to watch' for discovered Reels, and 'skip rate' or 'abandonment rate' would measure efficiency and dissatisfaction. Qualitative signals like user feedback or survey scores related to discovery experience would also be crucial. Finally, A/B testing different ranking algorithms or UI changes and measuring these metrics would be the practical application.

15. Q15

    Monetization increased for Marketplace, but meaningful social interaction rate and satisfaction declined. How would you frame the tradeoff?

    MediumProduct Analytics & Business CaseProduct AnalyticsMeta-specific

    Context: Quantify incremental revenue, user harm, partner impact, and reversibility.

    How to answer: A strong candidate would frame this as a classic short-term monetization vs. long-term user engagement/retention tradeoff. They should identify potential causal links, such as aggressive ad placement or transaction-focused UI changes, that might have boosted revenue but detracted from the social experience. The answer should then propose a framework for evaluating this tradeoff, likely involving LTV, churn rates, and user sentiment analysis, to determine if the monetization gains are sustainable or if they're cannibalizing the product's core value proposition. Finally, they would suggest A/B testing or controlled experiments to find an optimal balance.
