You’re not alone. Many people know the syntax — but struggle to solve problems that look messy, business-driven, and open-ended. That’s exactly why I built this course: your SQL Interview Kit (2025). Inside, you’ll practice 100+ real challenges, inspired by actual company interviews and day-to-day tasks faced by analysts and engineers.
What Makes This Course Different
This isn’t a theory dump. It’s hands-on problem solving. Every challenge puts you in the shoes of an analyst solving for a product, a business team, or a client.
Here’s what you’ll tackle:
- E-commerce & product funnels → find drop-offs, repeat buyers, cart abandoners.
- Banking & finance → detect risky trades, track customer tenure, calculate percentiles.
- Healthcare & fitness → retention metrics, patient gaps, appointment delays.
- Media & OTT apps → session streaks, genre trends, cross-platform users.
- Operations & logistics → shipping delays, courier performance, returns.
Along the way, you’ll also learn to spot patterns:
- When to use joins vs anti-joins
- How to choose between window functions vs GROUP BY
- How to debug issues with NULLs, duplicates, and overlaps
- How to explain your query clearly under interview pressure
How You’ll Learn:
- Every problem comes with a structured hint and a clean solution.
- Many challenges also include video walkthroughs — where I guide you through the thought process step by step.
- Sections are organized like an interview itself: starting simple, building up to complex case studies.
