Go (Golang) Interview: 200 Questions and Answers

The book "Go (Golang) Interview: 200 Questions and Answers" is a practical guide for those who want to confidently pass a technical interview for a Go developer position. The author has collected the most common and tricky questions asked in IT companies and provided detailed, structured answers.

The book covers all key topics: from syntax basics to advanced concepts of concurrency and performance optimization. Each question is accompanied not only by the correct answer but also by an explanation of why it is important to know for an interview. You will learn not just to answer, but to reason like an experienced Go developer.

What you will learn from the book:

• How goroutines, channels, and the Go scheduler work — and what questions about them are asked most often
• The difference between interfaces, structs, and generics in Go 1.18+
• How to manage memory: escape analysis, GC, stack vs heap
• Typical mistakes when working with concurrency (deadlock, race condition, goroutine leak)
• Best practices for writing clean, testable, and performant code
• How to answer questions about microservice architecture, HTTP servers, and database work

Who this book is for:

• Junior developers — systematize your knowledge and learn what to expect at your first interview
• Middle developers — fill gaps in theory and prepare for architecture questions
• Team Leads and tech leads — you can use the book as a checklist for evaluating candidates
• Anyone transitioning to Go from other languages — quickly master the specifics of the language through the lens of interviews

The book is structured on the principle of "question → answer → explanation." At the end of each chapter, there is a brief summary and tips for successfully passing the interview. 200 questions are divided into 10 thematic sections so you can study in parts. As a bonus — code examples that you can run and test immediately.
