Master Spring Boot, then nail the interview
Spring Boot, Spring Data JPA & Hibernate, Spring Security, Spring AI, Kafka and Spring Cloud — IoC, ORM internals, REST APIs, JWT auth, RAG, tool calling, MCP, resilience patterns, distributed transactions and production operations — full story-driven chapters to learn it from scratch, plus a real interview question bank to prove you know it.
What's inside
Learn From Scratch
Story-driven chapters that build every concept from first principles — dependency injection, the filter chain, RAG pipelines, partition assignment — with real Java/Spring code throughout.
Real Interview Questions
A curated question bank drawn straight from the material, with an AI tutor that builds a complete zero-to-expert answer for every question, on demand.
Diagrams, Chat & Flashcards
Generate a visual diagram for any topic or question, ask the AI tutor a follow-up, and review with spaced-repetition flashcards that bring weak spots back sooner.

Frequently Asked Questions
What are the most commonly asked Spring Boot interview questions?
Interviewers commonly ask about the Spring bean lifecycle, dependency injection types, how @Transactional and its propagation levels work, the N+1 query problem in Spring Data JPA, JWT authentication with Spring Security, and how Kafka consumers guarantee exactly-once processing — all covered here across dedicated chapters and an interview question bank.
Is Spring Data JPA the same as Hibernate?
No — JPA is a specification, Hibernate is the most common implementation of it, and Spring Data JPA is a further abstraction layer on top that auto-generates repository methods. This course's Spring Data JPA & Hibernate Mastery section covers all three layers and exactly how they relate.
How do I prepare for a Spring Boot microservices interview?
Focus on Spring Cloud patterns (service discovery, circuit breakers, API gateways), distributed transaction patterns (Saga, Outbox), and Kafka-based event-driven communication — this course's Spring Cloud and Kafka chapters build each from a real production scenario before the formal interview-style definition.
