REAL SQL Interview Question | Data Analyst, Data Engineer & BI Roles

⚠️ This is a REAL SQL interview-style question commonly used in analytics and business intelligence roles. In this video, I walk through a realistic SQL coding interview question where we build a daily customer-level revenue summary from scratch — exactly the kind of problem you’d see in a live SQL interview. What this SQL interview question covers: ✔️ Paid orders only ✔️ One row per customer per day ✔️ Gross revenue (quantity × price) ✔️ Discounts and refunds ✔️ Net revenue calculation ✔️ Flagging whether the day was the customer’s first purchase ✔️ Clean, interview-ready SQL using CTEs, joins, aggregation, and business logic This is not about memorizing syntax — it’s about: ✔️ Structuring your query ✔️ Explaining your logic clearly ✔️ Handling real-world business requirements If you’re preparing for SQL interviews, analytics roles, or business intelligence positions, this walkthrough will help you think like an interviewer expects. 🔗 ESSENTIAL LINKS 👉 Support my work: https://buymeacoffee.com/mehranvahedi 👉 Explore my Skillsoft courses: https://linktr.ee/MySkillsoftCourses 👉 Book a personal mentoring session: https://topmate.io/mehran_vahedi 👉 Follow for daily insights: https://x.com/WisdomByData 👉 Connect professionally on LinkedIn:   / mehranvahedi   📌 Tip: Watch until the end to see how interviewers expect you to explain CTEs, joins, COALESCE, and first-purchase logic clearly under time pressure. 🔖#SQLInterview, #SQLInterviewQuestions, #DataAnalytics, #BusinessIntelligence, #SQLTutorial, #AnalyticsInterview, #DataAnalyst, #BIAnalyst, #SQLForAnalytics, #CodingInterview, #TechInterviews, #DataCareers, #CareerInTech
