One of the MOST COMMON SQL interview questions is the Employee–Manager Hierarchy problem.
It looks simple, but most candidates make mistakes because they memorize queries instead of understanding the logic.
In this video, I’ll walk you step by step through solving these TWO tricky SQL questions:
1️⃣ How to display each employee along with their manager’s name
2️⃣ How to calculate the hierarchy level of each employee (CEO → Managers → Employees)
We will solve it using:
✅ Self Join to map Employee and Manager names
✅ Recursive CTE to find hierarchy levels
By the end of this video, you will not just memorize the answer — you’ll truly understand it.
So the next time this comes up in your interview, you’ll solve it with confidence.
