Comprehensive Collection of Interview Questions and Answers for Major Tech Companies (Java, Spring, Redis, MyBatis, etc.)

The author emphasizes that technical skill and experience come from long‑term practice, and that interview success also depends on mastering common interview questions and techniques. Over the weekend, a collection of recent big‑tech interview topics and classic questions, along with popular technical video resources, was assembled and shared for free.

The material covers a wide range of backend technology stacks, including Java basics, multithreading and concurrency, MyBatis, ZooKeeper, Dubbo, Elasticsearch, Memcached, Redis, MySQL, Spring, Spring Boot, Spring Cloud, RabbitMQ, Kafka, Linux, and more. It contains thousands of interview questions with detailed technical analysis, enabling rapid skill improvement.

Readers are encouraged to systematically review the questions, deeply study the patterns and pitfalls of major‑company interviews, and aim to stand out during the interview process.

To obtain the complete interview‑question document and answer explanations, scan the QR code in the article, follow the "Tuling Classroom" WeChat public account, and reply with the keyword "面试资料" (interview material).

Sample questions include Java fundamentals (e.g., object‑oriented features, access modifiers, primitive vs. wrapper types), concurrency topics (e.g., daemon vs. user threads, thread pools, atomic operations, lock interfaces), Spring framework concepts (e.g., IOC container, dependency injection, bean scopes), Redis concepts (e.g., data types, persistence, clustering, eviction policies), and MyBatis details (e.g., mapping files, dynamic SQL, caching, pagination).

The collection aims to help candidates efficiently prepare for interviews with major tech firms, saving time spent searching for scattered resources online.
