No thanks, I'll skip the free cheat sheetsThis free SQL interview simulator drills 61 real questions the way they actually get asked in SDET interviews. Reveal the answer, then face the interviewer’s follow-up — and see how often each question comes up so you spend time where it counts. Filter by joins, indexing, GROUP BY and subqueries, or switch to one-by-one practice mode.
Every card shows a real SQL interview question with its difficulty and an “asked %” that reflects how frequently it appears. Read the question, answer it out loud or in your head, then reveal the model answer and the code. The moment you do, the interviewer’s follow-up appears — the same way a real panel drills deeper — so you practise the second and third question, not just the first.
Use the high-frequency only filter to narrow the set to the questions asked 80%+ of the time. Those are your highest-return study set the week before an interview. Once those feel automatic, widen the net to medium and hard questions, and use practice mode to simulate the pressure of answering one at a time against the clock.
Yes. It runs entirely in your browser with nothing to install, and it is free for interview preparation.
It includes 61 real SQL interview questions, each with a model answer, code where relevant, and a follow-up question.
It is an estimate of how often that question appears in interviews, so you can prioritise the ones most likely to come up.
Start with the high-frequency questions, answer out loud before revealing the answer, and always attempt the follow-up — that is where most candidates get caught.
