Here are 15 technical interview questions with sample answers for a Software Developer position at Oracle with 0 to 2+ years of experience:

1. Question: Can you explain the difference between a primary key and a unique key in a database?

   Answer: A primary key is a column that uniquely identifies each record in a table, and it cannot contain NULL values. A unique key, on the other hand, enforces the uniqueness of values in a column but allows NULL values.

2. Question: Describe the SOLID principles in object-oriented design. How do they impact software development?

   Answer: The SOLID principles (Single Responsibility, Open-Closed, Liskov Substitution, Interface Segregation, Dependency Inversion) are guidelines for writing maintainable and scalable code. They promote modularity, extensibility, and code reusability.

3. Question: What is the purpose of an ORM (Object-Relational Mapping) framework, and can you name a few commonly used ones?

   Answer: ORM frameworks bridge the gap between object-oriented code and relational databases, allowing developers to work with databases using object-oriented concepts. Common ORM frameworks include Hibernate, Entity Framework, and SQLAlchemy.

4. Question: Explain the concept of RESTful APIs. What are the key HTTP methods used in REST?

   Answer: RESTful APIs use HTTP methods like GET, POST, PUT, and DELETE to perform CRUD (Create, Read, Update, Delete) operations on resources. They follow a stateless and client-server architecture.

5. Question: How do you handle concurrency and prevent race conditions in multi-threaded applications?

   Answer: Concurrency control mechanisms like locks, semaphores, and thread-safe data structures can be used to prevent race conditions. Additionally, using synchronized blocks and applying proper design patterns can help manage concurrent access to shared resources.

6. Question: What is the difference between synchronous and asynchronous programming, and when would you use each approach?

   Answer: Synchronous programming blocks the execution until a task is completed, while asynchronous programming allows tasks to run concurrently. Asynchronous programming is suitable for tasks that may take time, like I/O operations, to prevent blocking the main thread.

7. Question: Can you explain the concept of design patterns? Give an example of a design pattern and its use case.

   Answer: Design patterns are reusable solutions to common software design problems. For example, the Singleton pattern ensures that a class has only one instance and provides a global point of access, useful for managing a shared resource like a database connection.

8. Question: How do you optimize the performance of a web application? Mention some techniques and best practices.

   Answer: Performance optimization includes minimizing database queries, using caching, reducing network latency, optimizing code, and employing Content Delivery Networks (CDNs) for static assets.

9. Question: What is the importance of unit testing in software development, and what tools or frameworks are you familiar with for unit testing?

   Answer: Unit testing ensures that individual components of the software work as expected. I'm familiar with testing frameworks like JUnit, NUnit, and pytest for writing and running unit tests.

10. Question: Explain the concept of version control, and which version control systems have you used?

    Answer: Version control helps track changes in code, collaborate with team members, and manage code history. I have experience with Git, which is widely used in the industry, and tools like GitHub and GitLab for code collaboration.

11. Question: Can you describe the differences between functional programming and object-oriented programming? Provide examples of when to use each paradigm.

Answer: Functional programming emphasizes immutability, pure functions, and declarative coding. Object-oriented programming focuses on encapsulation and modeling real-world entities. Use functional programming for data transformations and object-oriented programming for modeling complex systems.

12. Question: How would you handle a critical bug in a production system? Describe your troubleshooting and debugging process.

    Answer: I would start by identifying the root cause through logs and error messages. Then, I'd replicate the issue in a development environment, analyze the code, and fix the bug. After testing and validation, I would deploy the fix to production.

13. Question: What is the significance of continuous integration and continuous deployment (CI/CD) in the software development process?

    Answer: CI/CD automates the testing and deployment of code changes, ensuring that new features and fixes are integrated into the production environment smoothly. It enhances development agility, reduces errors, and accelerates software delivery.

14. Question: Explain the concept of microservices architecture. How does it differ from a monolithic architecture?

    Answer: Microservices architecture breaks down an application into smaller, independent services that can be developed and deployed separately. In contrast, a monolithic architecture has a single codebase. Microservices offer flexibility and scalability but add complexity.

15. Question: Can you discuss your experience with cloud platforms like Oracle Cloud, AWS, or Azure? How would you choose a cloud platform for a specific project?

    Answer: I have experience with Oracle Cloud and AWS. When selecting a cloud platform, I consider factors such as scalability, cost, specific services required, and existing expertise within the team. The choice depends on the project's needs and goals.

These questions and answers should help you prepare for a technical interview for a Software Developer position at Oracle, whether you have 0 to 2+ years of experience. Be ready to discuss your experiences and demonstrate your technical knowledge during the interview.
