You can filter a table but freeze the moment a job test asks for a window function or a self-join.
Random YouTube videos in random order don't build toward a job-ready skillset. A roadmap does.
Real interviews probe CTEs, performance tuning and query optimization — not just SELECT * basics.
Core syntax, filtering, joins and the mental models that everything else builds on.
Window functions, CTEs, subqueries and performance tuning for real datasets.
Apply what you've learned to BI-style projects you can show in an interview.
Real questions from real companies, with worked solutions and a prep checklist.
This free cheatsheet and roadmap is better than most paid courses I've bought. I finally understand SQL properly.
The best free SQL resource I've found. Clear, practical, and exactly what I needed to move roles.
Used the 12-week plan almost exactly as laid out. Landed interviews within two months of finishing it.
The window functions and CTE section alone cleared up months of confusion from scattered YouTube videos.
