What is this?
A curated collection of real technical interview questions and answers from major Chinese tech companies — Alibaba, Tencent, Baidu, Meituan, ByteDance and more — with analysis from expert interviewers.
Is this a tool or a reading list?
It's a plain markdown reference document, not an app or library — just questions and answers organized for study.
Are the answers vetted or just crowd-sourced?
The README claims answers come with analysis from expert question-setters, but there's no stated review process or correctness guarantee beyond that claim.
Which companies' interview questions are included?
Alibaba, Huawei, Baidu, Tencent, Meituan, ByteDance (头条), Didi and JD each get their own chapter.
Does it cover algorithms and system design, or just databases?
Both — besides company-specific chapters there are dedicated sections on algorithms, memory, CPU, disk, networking, security and concurrency, plus MySQL, Redis, MongoDB, Zookeeper and Nginx.
Is the content in English?
No, every question and answer in the repository is written in Chinese.
