Customer Journey and Funnel Optimization Questions

Covers analysis and optimization of user conversion funnels and the broader customer journey from initial awareness through acquisition, onboarding, activation, monetization, retention, and advocacy. Core skills include mapping multichannel touchpoints, defining funnel stages and key metrics, constructing and querying funnels, creating funnel visualizations, measuring stage conversion rates and transition probabilities, and identifying friction points and drop off stages. Candidates should demonstrate cohort and segmentation analysis, calculation and use of lifetime value and customer acquisition cost, and diagnosis of root causes using both quantitative signals and qualitative research. Work also covers instrumentation and clean event design to ensure data quality, meaningful reporting that ties funnel improvements to business outcomes, and prioritization frameworks that weigh volume, expected lift, and downstream impact. Candidates should be able to design controlled experiments and split tests with appropriate measurement windows and power considerations, measure incremental and downstream effects, and recommend tactical interventions such as onboarding improvements, progressive disclosure, checkout and signup friction reduction, personalization, nurturing, and lead scoring. Finally, candidates should translate analytics into data driven roadmaps and product or marketing experiments that move business metrics such as revenue and retention.

You have 12 candidate funnel experiments with estimated weekly exposure volume, expected percentage uplift, engineering effort in weeks, and uncertainty scores. Propose a prioritization formula that balances expected impact, effort, and uncertainty and show a sample calculation for two hypothetical experiments. Explain how you'd present these priorities to product and marketing stakeholders.

Write a DAX expression (Power BI) to compute a rolling 7-day unique-user conversion rate where numerator is distinct users who performed 'purchase' in the last 7 days and denominator is distinct active users in the same period. Assume Events table with EventDate and EventName and a Users table. Explain performance considerations.

Design an experiment to measure incremental long-term LTV uplift from a redesigned onboarding flow when most monetization occurs after 90 days. Explain measurement windows, surrogate early metrics, use of holdouts, progressive rollouts, and statistical analysis to estimate downstream effects and uncertainty.

Design a minimal event schema for tracking an e-commerce purchase funnel with events: page_view, product_view, add_to_cart, begin_checkout, purchase. For each event specify required properties (e.g., user_id, session_id, product_id, price, currency, SKU, quantity, timestamp) and explain why each property is important for funnel analysis, deduplication, and revenue calculations.

You have funnel data showing 30% of users drop at step 2. Propose three plausible, testable hypotheses for why users drop off, and design specific A/B tests or quick experiments for each hypothesis including metric definitions and an outline of required sample size considerations.
