Rust Interview: 200 Questions and Answers

This book is your personal training tool for preparing for a technical interview in the Rust language. It contains 200 carefully selected questions with detailed answers that cover all key topics: from basic syntax to complex concepts like unsafe code and asynchronous programming.

Who is this book for?

• Junior developers preparing for their first Rust position interview
• Middle and Senior programmers looking to systematize their knowledge
• Developers from other languages (C++, Go, Python) transitioning to Rust
• Tech leads who want to assess the depth of their team's knowledge

What will you learn?

• How the ownership, borrowing, and lifetimes system works
• Differences between traits and generics
• Principles of working with smart pointers: Box, Rc, Arc, RefCell
• How to write safe concurrent code using threads and channels
• Features of asynchronous Rust: Future, async/await, tokio
• When and how to use unsafe Rust
• Common interview mistakes and how to avoid them

Each question is accompanied not only by the correct answer but also by an explanation — why the answer is what it is, what pitfalls exist, and how this topic is tested in real interviews. Questions are divided by difficulty level: from basic (for beginners) to advanced (for senior positions).

The book is structured so that you can use it both for sequential study and for quick knowledge checks before an interview. At the end of each chapter, there is a list of self-test questions and recommendations for in-depth study of the topics.

The author is a practicing Rust developer with 5 years of experience, a participant in open-source projects, and a technical interviewer at a large product company. All questions are based on real cases from interviews in Russian and international IT companies.

Regardless of your current level, this book will help you feel confident in an interview and demonstrate a deep understanding of one of the most in-demand programming languages of our time.
