## 🌟 Why this book is different

✅ **Understanding first.** Answers explain *why* Git behaves as it does, not just which command to type.

✅ **Interview-shaped.** Questions mirror real interviews, from warm-ups to senior-level deep dives.

✅ **Practical.** Short, runnable examples in every chapter.

✅ **Modern.** Covers newer commands such as `git switch` and `git restore` alongside the classic forms.

✅ **Scenario practice.** Part 10 trains the calm "diagnose, act safely, verify, prevent" answer that senior interviewers love.
