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 an abstract class and an interface in Java.
Look for: An abstract class can provide both abstract and concrete methods, has state, and allows constructor usage. An interface (pre-Java 8) can only declare abstract methods; Java 8+ interfaces can have default and static methods but no instance fields. Use abstract classes for shared implementation, interfaces for contracts.
2. How does Java manage memory?
Look for: Java uses the JVM with a heap for object allocation and a stack for method frames. Garbage collection automatically frees unreachable objects, with algorithms like G1, CMS, or Serial optimizing throughput and pause times.
3. What is the purpose of the 'final' keyword?
Look for: 'final' can declare constants, prevent method overriding, and stop class inheritance. It ensures immutability of variables and guarantees that a method’s behavior cannot be altered in subclasses.
4. Describe how you would implement a RESTful API endpoint in Spring Boot.
Look for: Create a @RestController with @RequestMapping, define a method annotated with @GetMapping/@PostMapping, inject a Service layer, and use a Repository for data access. Return DTOs and handle exceptions with @ControllerAdvice.
5. Explain a scenario where you would use a HashMap over an ArrayList.
Look for: Use a HashMap when you need fast key-based lookups (O(1) average), such as mapping user IDs to user objects, whereas an ArrayList is preferable for ordered collections with index-based access.
Interviewing guidance: Adapt follow-up questions to the candidate's experience and the actual system. Use the same core criteria consistently across candidates.

History and Background

Use this section for relevant history, origins, evolution or background related to the role, discipline, technology, business function, industry or process.

Java was introduced by Sun Microsystems in 1995 and quickly became a dominant language for enterprise applications due to its platform independence, robustness, and rich ecosystem. As organizations adopted Java EE/J2EE for large-scale web and business systems, demand grew for developers who could support coding, testing, and maintenance activities. The Junior Java Developer role emerged as an entry point into enterprise software teams, allowing organizations to train early-career talent on Java stacks while senior engineers focused on architecture and complex design. Over time, the role has evolved from JSP/Servlet and EJB-based development to Spring and Spring Boot, REST APIs, microservices, cloud deployment, and DevOps practices. In India, the role expanded significantly with the growth of IT services, global capability centers, and product startups, making it a common fresher/entry-level position that emphasizes core programming fundamentals, database skills, and agile delivery.
