Top 5 Interview Questions

Use these questions to assess practical judgement, role knowledge and applied problem-solving. Expand each one for answer signals.

1. Explain the difference between checked and unchecked exceptions in Java.
Look for: Checked exceptions must be declared or caught; they represent recoverable conditions. Unchecked exceptions (RuntimeException) are not required to be declared and usually indicate programming errors.
2. How does Spring Boot simplify application configuration?
Look for: It provides auto-configuration, opinionated defaults, and embedded servers, reducing XML/annotation boilerplate and enabling rapid startup.
3. Describe a strategy to handle database transactions in a microservice.
Look for: Use Spring’s @Transactional for local transactions, implement idempotent operations, and consider distributed transaction patterns like Saga or two-phase commit when necessary.
4. What is the purpose of the Java Memory Model and how does it affect multithreaded code?
Look for: It defines how threads interact through memory, ensuring visibility and atomicity. Proper use of volatile, synchronized, and concurrent collections prevents race conditions.
5. How would you design a RESTful API for a product catalog service?
Look for: Use resource-oriented URIs, support CRUD operations with appropriate HTTP verbs, implement pagination, filtering, and HATEOAS links, and secure endpoints with OAuth2.
Interviewing guidance: Adapt follow-up questions to the candidate's experience and the actual system. Use the same core criteria consistently across candidates.

Common role questions

Java Developer FAQs

What distinguishes a Mid-Level Java Developer from a Junior one?
Mid-Level developers independently design modules, lead code reviews, and mentor juniors, whereas Juniors focus on learning patterns and completing assigned tasks.
Which Java frameworks are most critical for this role?
Spring Boot for rapid microservice development, Hibernate/JPA for ORM, and Spring Cloud for distributed system patterns are essential.
How important is cloud experience for a Java Developer in India?
Highly important; many projects deploy Java services on AWS or GCP, so familiarity with cloud services, CI/CD, and container orchestration is a strong advantage.
What are common performance bottlenecks in Java applications?
Inefficient JDBC usage, excessive object creation, poor caching, and thread contention are typical bottlenecks that developers should monitor.
Is knowledge of Java 17 mandatory?
While Java 17 is the current LTS, many enterprises still use Java 11; however, familiarity with the latest language features is beneficial.
