💬 Potential Interview Questions

How do you design and implement scalable microservices using Spring Boot with Java or Kotlin?
Use modular architecture, define clear API contracts, apply dependency injection, and utilize Spring Boot’s built-in tools for configuration, security, and monitoring.
What are the main differences between Neo4j and MySQL, and when would you use each?
Neo4j is a graph database ideal for complex relationships and traversals, while MySQL is relational, better suited for structured, tabular data and ACID compliance.
How do you ensure smooth integration between Angular or React frontends and Spring Boot backends?
Use RESTful APIs or GraphQL, manage CORS policies, structure endpoints logically, and employ client-side state management and service layers.
What are best practices for optimizing front-end performance in Angular or React applications?
Use lazy loading, memoization, efficient state management, and code splitting. Minimize DOM updates and use tools like Lighthouse for audits.
How do you structure data access layers for performance and scalability in Spring Boot?
Use JPA/Hibernate with query optimization, pagination, connection pooling, and indexing strategies. For Neo4j, apply efficient Cypher queries.
What testing strategies do you use in full-stack applications?
Implement unit, integration, and contract tests using JUnit, Mockito, Postman/Newman, and end-to-end tools like Cypress or Selenium.
How do you manage CI/CD for full-stack projects involving both Java/Kotlin and JavaScript frameworks?
Use tools like Jenkins, GitHub Actions, or GitLab CI; separate pipelines for front- and back-end; automate testing and deployment with Docker and Kubernetes.
What are key considerations when designing APIs for real-time data synchronization?
Ensure low latency, support WebSockets or Server-Sent Events, handle reconnections, and implement rate limiting and proper serialization.
How do you mentor and lead full-stack engineers effectively?
Provide constructive code reviews, set technical goals, facilitate knowledge sharing, pair programming, and lead by example in documentation and architecture.
What security best practices do you follow in full-stack development?
Use HTTPS, sanitize inputs, apply authentication/authorization, secure APIs with OAuth2/JWT, and configure secure headers and CSRF protection.
