Based on feedback from employers, we have created a comprehensive SQL test document designed to prepare you for common SQL interview questions. This test covers all the essential SQL functions that are frequently tested in interviews, helping you build a strong foundation.
Basic SQL Functions: We will start with basic operations like SELECT, JOIN, WHERE, GROUP BY, and ORDER BY.
Advanced SQL Concepts: As you progress, you'll work with more technical concepts, including CASE statements and creating VIEWS to aggregate data.
This document aims to ensure you feel confident using SQL in interviews and in practice. Understanding these concepts is essential to having SQL listed on your resume and being prepared to discuss and apply these skills in a real-world environment.
