About this course

Technical interviews often require proven proficiency in both general programming (Python) and efficient data manipulation (SQL). This course provides the foundational knowledge and practical structure necessary to excel in both areas. You will move beyond basic syntax to applying intermediate Python structures and advanced SQL querying techniques. By the end, you will have the confidence and practical skills required to approach complex problems presented during technical screening processes. What you'll learn: * Understand core Python syntax, data structures, and control flow mechanisms. * Master foundational SQL commands for data definition, manipulation (CRUD), and filtering. * Apply advanced SQL querying concepts, including complex joins, aggregations, and Common Table Expressions (CTEs). * Practice writing idiomatic and maintainable Python code, incorporating basic type hints for improved readability. * Learn standard algorithms and data structure manipulation patterns frequently encountered in coding challenges. * Configure and interact with a local database environment to practice data retrieval skills. The course is structured to build parallel competency in both languages, starting with fundamental definitions and progressing through practical, assessment-style exercises. Each lesson emphasizes writing clear, readable code and efficient, optimized queries. This course is designed for absolute beginners in programming or data, or those preparing for their first technical role requiring dual proficiency in Python and SQL. No prior programming or database knowledge is required to start. Start building your technical interview confidence today.
