Kafka Interview Kit - 90 Questions & Answers with Sanjay

Kafka questions in backend interviews rarely stop at "what is a partition". Interviewers ask what happens when a broker dies mid-write, why a consumer group keeps rebalancing, or how to avoid charging a customer twice. This kit prepares you for those questions.

What you get:

- 50 core questions from fundamentals to internals, tagged Beginner, Intermediate or Advanced

- 20 scenario questions based on real work situations

- 10 Kafka system design questions

- 10 production troubleshooting scenarios with the exact CLI commands to diagnose them

- A quick revision sheet for the day before the interview

- 4 cheat sheets: Kafka 4.2 CLI, producer and consumer configs with defaults, Spring Boot 4 + Spring Kafka 4, troubleshooting checklist

- Written for Kafka 4.2 (KRaft), Java 21 and Spring Boot 4

- PDF

PLUS Kafka Design thinking course as a BONUS

Who it is for: Java and backend developers, senior engineers and tech leads preparing for interviews where Kafka or event-driven design comes up.
