If you don't know what you don't know, you can't prepare for it. The Skill Quiz generates a timed test on any topic, scores every answer, explains why you got it wrong, and recommends what to study next. It's the fastest way to find and fill the holes in your knowledge.
In the sidebar, expand AI Career Tools and click Skill Quiz. If you've taken quizzes before, you'll see your history and scores. Click "New Quiz" to start a fresh assessment.
Type the topic you want to be tested on. This can be anything: "System Design," "React Hooks," "SQL Joins," "Leadership," "Conflict Resolution," or "Data Structures and Algorithms." The more specific, the better the questions.
Easy is good for a warm-up or a topic you're new to. Medium matches what you'd see in a typical interview. Hard is designed for senior-level or specialized roles.
Choose how many questions you want in the quiz. A 10-question quiz takes about 10–15 minutes. A 25-question quiz gives you a more comprehensive assessment of your knowledge.
The quiz starts with a countdown timer. Read each question carefully, select your answer, and click Next. You can flag questions to come back to before submitting.
After submitting, you get an overall score and a detailed breakdown for every question. Each question shows the correct answer and a clear explanation of why it's right — including why the wrong answers are wrong.
At the bottom of the results page, the AI generates study recommendations based on your weak areas. If you missed all the questions about indexing in a SQL quiz, it'll tell you to focus on database indexing specifically.
