后端面试题汇总（Python、Redis、MySQL、PostgreSQL、Kafka、数据结构、算法、编程、网络）
A Chinese-language collection of backend interview questions covering Python, Go, Redis, MySQL, PostgreSQL, Kafka, data structures, and networking. It's primarily a study guide for developers preparing for technical interviews at Chinese tech companies. The Go section has the most original content; other sections lean heavily on external links.
The Go section includes working code examples for real concurrency questions — goroutine coordination, concurrent maps, channel edge cases — not just MCQ trivia. The data structures section has actual Python implementations rather than just links. Covers practical system design questions (flash sales, short URLs, feed systems) that come up in actual interviews. Breadth is genuinely useful as a checklist of topics to study.
Most sections outside Go are thin wrappers around WeChat public account article links — if those links rot (and they will), large chunks of the repo become dead ends. Last commit was July 2023; Redis, PostgreSQL, and Kafka content hasn't been touched since, so anything about recent versions is missing. No Kafka-specific question content exists despite it being listed as a topic — the middleware README is a placeholder. The repo is almost entirely in Chinese, which is fine for its audience but the README gives no signal that English speakers will find anything useful here.
