Conducted by a tech panel (1 or 2 rounds). Expect:

Core SQL queries: joins, window functions, subqueries

Data structures and algorithms (for dev roles)

Scenario-based questions: e.g., "How would you optimize a slow query?" or "How do you design a normalized schema for a stock trading platform?"

Project discussion: Walkthrough of your past experience, especially if you’ve worked with databases, reporting, or analytics tools.
