Query Dojo vs SQLite

Walk into your SQL interview ready. Query Dojo is SQL interview practice that fits in a few minutes a day. Drill the classic questions, rehearse under a real interview clock, and see exactly what is wrong when a query fails. PRACTICE THE CLASSIC QUESTIONS 85 interview-style SQL challenges, from finding the runner-up salary to top earners per department, monthly retention, login streaks, running totals and medians. Every query runs on a real database, right on your phone. REHEARSE UNDER A REAL CLOCK Timed mock interviews: 25 minutes, 4 questions, no hints. Finish with a readiness score out of 100, so you know where you stand before the real thing. SEE EXACTLY WHY AN ANSWER IS WRONG Every run is checked against the expected result. When it is off, you see what is missing or extra, from columns to rows. Hints and full solutions are there when you are stuck. BUILD QUERIES WITHOUT A KEYBOARD Tap tiles to build real queries, put lines in the right order, or type from scratch. RELEARN WHAT YOU FORGOT 79 bite-size lessons, from SELECT and JOINs to window functions, CTEs, gaps and islands, and finding the median. A PLAN FOR YOUR LEVEL Tell us where you are and get a 4-week belt plan with the topics to focus on first. EARN YOUR BLACK BELT Every challenge and lesson moves you up, from white belt to black belt and beyond, with streaks to keep you consistent.
