Top Java & Spring Boot Interview Questions

Real-world problems. Senior-level thinking. Better interview preparation.

A growing library of real-world Java & Spring Boot interview questions designed for engineers preparing for junior, senior and staff-level interviews.

Forget questions that test whether you can memorize an API.

Instead, practice problems involving concurrency, Kafka, databases, caching, Spring Boot, performance, distributed systems, debugging, and production failures.

85+ interview problems published and counting. New interview problems are added regularly (2 questions per week).
