"Core Java Knowledge: * Deep Understanding of Java: Proficiency in core Java concepts, including data structures (ArrayList, HashMap, HashSet, LinkedList, etc.), control flow (loops, conditionals), exception handling (try/catch), and methods. * Advanced Java Features: Knowledge of advanced features like generics, lambdas, streams, functional interfaces, and Java's concurrency mechanisms (Threads, ExecutorService, etc.). * Object-Oriented Programming (OOP): Proficiency in OOP principles, including classes, inheritance, polymorphism, encapsulation, and abstraction. 2. Experience with Libraries and Frameworks: * Web Frameworks: Experience with Java-based frameworks such as Spring (Spring Boot, Spring MVC), Hibernate, or Java EE. A 4-year Java developer should be comfortable building and deploying web applications, including managing controllers, services, and repositories. * Data Handling: Experience with libraries such as Apache Commons, Jackson (for JSON processing), or any similar Java libraries used for data processing and manipulation. * REST APIs: Ability to design and consume RESTful APIs, using tools such as Spring Web, Spring Boot, or JAX-RS. * Database Knowledge: Strong understanding of SQL and ORM tools like Hibernate, JPA, or Spring Data JPA. Familiarity with both relational databases (MySQL, PostgreSQL) and NoSQL databases (MongoDB). * Testing: Familiarity with unit testing frameworks like JUnit, TestNG, and mocking libraries like Mockito. 3. Version Control: * Git: Experience with Git for version control, including branching, merging, pull requests, and resolving merge conflicts. Knowledge of Git best practices in collaborative environments. 4. Working with External Services: * APIs and External Integrations: Experience integrating third-party services via APIs, handling authentication (OAuth, JWT), and working with cloud-based services like AWS, GCP, or Azure. * Task Queues: Knowledge of task queues and asynchronous processing tools like Apache Kafka, RabbitMQ, or ActiveMQ for handling background tasks and messaging. 5. DevOps Knowledge (Good to have): * CI/CD: Familiarity with Continuous Integration and Continuous Deployment (CI/CD) pipelines using tools like Jenkins, GitLab CI, CircleCI, or Travis CI. * Containerization: Experience with Docker for containerization and Docker Compose for managing multi-container applications. * Cloud: Familiarity with deploying applications to cloud platforms such as AWS, Azure, or Google Cloud, and using Kubernetes or similar tools for application orchestration and scaling. 6. Problem Solving & Algorithms (Very Important): * Algorithmic Thinking: Ability to solve medium-to-high complexity problems with optimal algorithms. Familiar with common algorithms and data structures like sorting algorithms, trees, graphs, stacks, and queues. * Efficiency and Optimization: Ability to analyze performance bottlenecks and optimize code where necessary (e.g., improving time complexity, memory usage). 7. Soft Skills: * Code Reviews: Ability to conduct and receive constructive code reviews, ensuring code quality, readability, and maintainability. * Communication: Strong communication skills, especially when discussing technical problems or explaining code to non-developers. Clear documentation of code and processes. * Collaboration: Ability to work effectively in a team, collaborating with front-end developers, product managers, and designers, and following agile methodologies (Scrum, Kanban). * Mentorship: Expected to mentor junior developers, helping them improve their coding skills, debugging techniques, and knowledge of Java. 8. Security Best Practices: * Secure Coding: Knowledge of common security vulnerabilities (SQL injection, cross-site scripting, cross-site request forgery, etc.) and how to mitigate them. * Authentication and Authorization: Implementing secure user authentication (OAuth, JWT, 2FA) and understanding common security protocols and encryption methods. 9. Framework-Specific Expertise: * Spring Framework: Deep understanding of Spring (Spring Boot, Spring MVC, Spring Security, Spring Data). Experience with creating RESTful APIs and microservices using Spring Boot. * Hibernate: Strong understanding of Hibernate ORM, JPA, and entity relationships (one-to-many, many-to-one). * Spring Cloud: Familiarity with microservice architecture and tools like Spring Cloud for building distributed systems. 10. Version Control and Collaboration: * Working in Agile Environments: Comfortable working in Agile environments, participating in daily standups, sprint planning, and retrospectives. * Collaborative Workflow: Knowledge of collaborative tools like Jira, Confluence, or Trello. 11. Documentation and Code Quality: * Documentation: Ability to document APIs, code, and systems effectively, both for internal and external use. * Code Style: Adherence to Java best practices and coding standards, such as using effective variable names, following the Java Namin
