What This Repository Is

This is a study guide and reference collection for people preparing for Go programming job interviews. It contains dozens of real interview questions, complete with explanations and solutions, organized by topic. Think of it as practice materials that cover the kinds of problems you're likely to encounter when interviewing for a Go developer role.

What's Inside

The collection breaks down into several areas. The core section is Go-specific interview questions—things like writing code to alternate between printing numbers and letters, finding unique characters in strings, or building thread-safe data structures using Go's concurrency features (goroutines and channels). Beyond coding problems, there's also theory coverage of how Go's scheduler works under the hood and common gotchas like memory leaks in HTTP handling.

The repository also branches into related topics that frequently come up in technical interviews: Redis (an in-memory database), MySQL (relational databases), and classic computer science algorithms like string matching and sorting. These aren't Go-specific, but they're part of the broader knowledge base that strong backend engineers are expected to know.

Who Would Use This

If you're a software engineer preparing to interview for a Go-focused backend role—especially at larger tech companies—this is a practical reference. You could work through the questions to get comfortable with how Go handles concurrency, memory management, and standard library features. Interviewers preparing their own question bank might also browse this to see what kinds of problems are commonly asked. The mix of coding challenges, theoretical questions, and algorithm problems mirrors what you'd actually face in a real interview loop.

How It's Organized

Each question gets its own page with an explanation and solution. The structure lets you jump to whatever topic you need to study—whether that's understanding goroutine scheduling, fixing buggy code snippets, or refreshing your knowledge of data structures. It's a reference you'd likely revisit multiple times as you prepare, rather than something you read straight through.
