About the project

Apache Kafka for Senior Java Interviews is free, open source material created to help Java Backend developers prepare for Apache Kafka technical interviews — from architecture fundamentals to delivery guarantees, idempotency, and observability.

This content doesn't replace the official Apache Kafka documentation or the hands-on experience of running the system in production. It exists to consolidate and organize the knowledge needed to explain these concepts confidently in an interview — and, as a result, in the day-to-day work of anyone already using the tool.

Contributions are welcome: technical corrections, new chapters, new interview questions, or accessibility and design improvements can be proposed directly in the project's repository.
