We start with the easy-level "Team Power Users" problem, where I break down how to identify the top two power users who sent the most messages on Microsoft Teams during August 2022. I explain how to filter dates, use GROUP BY statements, and implement subqueries to get the correct results. Then we move on to the medium-difficulty "Supercloud Customer" question, where we need to identify companies that purchase at least one product from every category. I demonstrate how to join multiple tables, count distinct product categories, and build a comprehensive query that compares customer purchases against total product categories. Throughout both problems, I share my thought process for breaking down requirements, choosing the right SQL functions, and debugging errors. By the end of this video, you'll understand how to approach SQL interview questions systematically, avoid common mistakes, and write clean, efficient queries. These are the exact types of questions asked at Microsoft and other top tech companies, so if you're preparing for data analyst or data engineer interviews, this walkthrough will help you build confidence and master SQL problem-solving techniques.
