📚 How to Study Effectively

1. Skim first: Read all the questions quickly to get an overview of what's covered.
2. Pick your sections: Based on your target role (see table above), select 3-4 sections to focus on.
3. Practice out loud: Read the question, cover the answer, and try to respond verbally as if in an interview. Then compare with the model answer. 4.. Use the follow-up questions: Each question has a "follow-up" question designed to test deeper understanding. Have a friend or study partner ask you these.
4. Do the exercises: The 7 practical exercises at the end will help you apply what you learned in real scenarios.

🎓 Interview Day Tips

• Arrive early and test your audio equipment if the interview is remote.
• Bring this handbook on your laptop or phone for quick reference before the interview (but don't use it during!).
• Think out loud: Interviewers want to hear your reasoning process, not just the final answer. .
• Use the STAR method for behavioral questions: Situation, Task, Action, Result. . . .

🛠️ What You Need

• A computer running Windows (any recent version works) or any device that can open a ZIP file and read a text document. .
• No special software required for the README file – Notepad works fine. If you prefer the HTML version, any modern web browser (Chrome, Edge, Firefox) will work.
