Interview Questions & Preparation
Java & Technical Questions
Q1. What are the key differences between Spring Boot and the traditional Spring Framework? Explain that Spring Boot provides auto-configuration, embedded servers, and starter dependencies to reduce boilerplate setup, while the traditional Spring Framework requires manual configuration of beans, dependencies, and server deployment.
Q2. How does Hibernate manage the relationship between Java objects and database tables? Explain that Hibernate uses Object-Relational Mapping (ORM) to map Java classes to database tables via annotations or XML configuration, handling the translation between object state and SQL operations automatically.
Q3. What is a microservices architecture, and what are its key benefits? Explain that microservices architecture breaks an application into small, independently deployable services, each responsible for a specific business capability, offering benefits like independent scaling, technology flexibility, and fault isolation.
Q4. How do microservices typically communicate with each other? Mention common approaches such as synchronous REST APIs, asynchronous messaging queues (like Kafka or RabbitMQ), and service discovery mechanisms that help services locate one another.
Q5. What is the N+1 query problem in Hibernate, and how would you resolve it? Explain that it occurs when Hibernate issues one query to fetch a list of entities and then a separate query for each related entity’s associations, and that it can be resolved using techniques like JOIN FETCH or batch fetching.
Q6. Which AWS services have you worked with, and how have you used them in your projects? Share specific examples, such as using EC2 for hosting applications, S3 for storage, or RDS for managed databases, and explain how they fit into your overall application architecture.
Communication & HR Questions
Q1. Tell me about yourself. Keep it short – mention your total years of experience, current/most recent role, and key technical skills such as Java, Spring Boot, Hibernate, or microservices.
Q2. Why do you want to join Amosta? Say that you are drawn to the opportunity to work on modern Java-based microservices projects, grow your technical skills, and contribute to a growing engineering team.
Q3. Can you join immediately? What is your current notice period? Be direct and clear about your actual notice period or availability, confirming it aligns with the immediate joining requirement for this role.
Q4. Describe a challenging project where you used Spring Boot and microservices. Share a specific example, explaining the business requirement, the technical architecture you designed or contributed to, the challenges faced, and how you resolved them.
Q5. How do you approach debugging a performance issue in a Java application? Explain that you would use profiling tools to identify bottlenecks, review database query performance, check for memory leaks, and validate fixes in a staging environment before deploying to production.
