How to practice
Use each answer as a speaking script, not just reading material.
Interview preparation works best when you can explain an answer in your own words. Use KASA to find the question, understand the expected points, then speak a short version and a detailed version.
- Search a role or topic before reading answers.
- Open one question and speak the answer aloud.
- Check expected points, mistakes, and follow-up questions.
- Add a better answer or comment when you have a clearer explanation.
