Question 1

How long does the quiz take?

Accepted Answer

Around 5 minutes. 10 multiple-choice questions, no time pressure on individual questions, no signup before you start. You can leave and return — your progress is saved in this browser tab.

Question 2

What level does the quiz determine?

Accepted Answer

0-3 correct = Beginner (you know some basics, need foundations). 4-6 correct = Intermediate (strong on basics, gaps on advanced patterns). 7-8 correct = Advanced (interview-ready, refine the rough edges). 9-10 correct = Expert (you know your stuff — start mock interviewing). The result screen also shows which skill areas you got right vs wrong.

Question 3

Is this enough to evaluate me for a job?

Accepted Answer

No. Real interview SQL is open-ended — write a query that produces this output from this schema. Multiple-choice quizzes test recognition; interviews test recall under pressure on novel data. The quiz tells you where to focus your prep, not whether you'd pass an interview tomorrow. For interview-ready practice, use SQL Quest's challenge bank (200+ problems with diagnostic feedback).

Question 4

Do I need to give my email?

Accepted Answer

No. The result screen shows your score, level, and study path with no signup required. There's an optional 'send results to my inbox' field if you want a written summary plus weekly-challenge reminders, but it's not required to see anything.

Question 5

What topics does the quiz cover?

Accepted Answer

10 topics, one question each: SELECT/WHERE/HAVING placement, ORDER BY default direction, INNER vs OUTER JOIN distinction, HAVING vs WHERE filtering, NULL three-valued logic, CASE expression placement, correlated subqueries, ROW_NUMBER vs RANK vs DENSE_RANK, recursive CTE structure, and anti-join NULL safety. Each question maps to a real interview topic.
