SQL Interview Question #10 🧵 Find employees who earn more than their manager. Sounds simple… but many candidates freeze. The tricky part is not the comparison. It’s understanding the relationship. Employees and managers are stored in the SAME table. manager_id → employee_id

SQL Interview Question #9 🧵 Find the top-selling product each month. Sounds like GROUP BY… but it’s more than that. Many candidates calculate total sales correctly… but get stuck finding the top product per month.

SQL Interview Question #8 🧵 Find days where temperature was higher than the previous day. Sounds simple… but many candidates struggle. The tricky part is not the comparison. It’s accessing the previous row correctly.

SQL Interview Question #7 🧵 Show current amount + previous amount in the same row. Sounds simple… but many people overcomplicate it. Most candidates think about self joins. But self joins can get messy quickly.
