The SQL questions are typically medium difficulty, involving joins, aggregations, window functions, and CTEs, often tied to real business scenarios like retention or funnel analysis. The coding questions (mostly in Python) lean toward easy to medium difficulty and cover arrays, strings, hashmaps, and 2-pointer techniques. Focus your prep on Meta-tagged LeetCode and StrataScratch problems, especially in SQL and data-heavy logic, and practice writing clean, performant queries.
