Day 5 Learning SQL to Get Hired

Welcome to Day 5 of my "Learning SQL to Get Hired" series!

Today, I’m working through two LeetCode SQL problems:
- #577 Employee Bonus
- #1280 Students and Examinations

What you'll learn:
- Using LEFT JOIN and handling NULL values in result sets
- Combining multiple tables with JOINs and GROUP BY
- Real-world use cases like reporting missing data and summarizing student performance

As always, I’m walking through my thought process, showing how I debug mistakes and explaining what I’d expect if this came up in an interview. Try these problems yourself and let me know how you approached them!
