Senior data analyst interviews often include SQL case studies focused on real business problems. Common questions involve customer churn analysis, sales trend analysis, cohort analysis, funnel conversion tracking, and performance optimization of complex queries. Interviewers expect candidates to explain logic clearly, use joins, subqueries, and window functions, and interpret results for decision-making. Strong preparation through hands-on Data analytics training helps candidates handle advanced SQL case studies confidently.
