Oracle Fusion is a suite of enterprise resource planning (ERP) applications developed by Oracle. Technical interviews for Oracle Fusion-related roles may cover a range of topics depending on the specific position, but here are some common technical interview questions and sample answers that may help you prepare:

1. What is Oracle Fusion Middleware? Oracle Fusion Middleware is a platform that provides a set of services and tools for building, deploying, and managing enterprise applications. It includes components for business process management, integration, identity management, security, and more.

2. Explain the concept of Oracle Fusion Applications. Oracle Fusion Applications are a suite of software applications built on top of Oracle Fusion Middleware. They offer a complete set of business applications, including ERP, CRM, HCM, SCM, and more, designed to work together and provide a comprehensive business solution.

3. What is the role of Oracle Application Development Framework (ADF) in Oracle Fusion? Oracle ADF is an MVC-based Java framework used for building enterprise applications. In Oracle Fusion, ADF is the primary framework for developing the user interface and integrating various components to create seamless user experiences.

4. How does Oracle Fusion differ from traditional Oracle E-Business Suite (EBS)? Oracle Fusion is a more modern and integrated suite of applications compared to the traditional Oracle EBS. Fusion applications are built using the latest technologies, designed to work together in a modular and extensible manner, whereas EBS applications were developed independently and later integrated.

5. Explain the concept of Oracle Fusion Security and Role-Based Access Control (RBAC). Oracle Fusion Security provides a robust RBAC system, which means access to various features and functions within the application is granted based on user roles and permissions. This ensures that users can only access the data and perform actions that are relevant to their job responsibilities.

6. What are Oracle Fusion Data Conversions? Data conversions in Oracle Fusion refer to the process of migrating and transforming data from legacy systems or older versions of Oracle applications to the new Fusion environment. This process is crucial when implementing Oracle Fusion to ensure that existing data can be seamlessly used in the new system.

7. Explain the architecture of Oracle Fusion Applications. Oracle Fusion Applications follow a service-oriented architecture (SOA) where various modules and services communicate with each other through standard protocols and interfaces. The architecture is designed to be scalable, flexible, and easily integrable with other systems.

8. What is Oracle WebCenter in Oracle Fusion Middleware? Oracle WebCenter is a component of Oracle Fusion Middleware that provides tools and services for building portals, content management systems, and collaboration applications. It enables organizations to create personalized and secure portals for users to access relevant information and collaborate effectively.

9. Describe the role of Oracle SOA Suite in Oracle Fusion. Oracle SOA Suite is a comprehensive suite of tools and services for building, deploying, and managing service-oriented architecture (SOA) applications. It plays a crucial role in Oracle Fusion by enabling integration between various applications and services within the suite.

10. How do you handle customizations and extensions in Oracle Fusion Applications? Oracle Fusion provides extension points and customization options that allow organizations to tailor the application to their specific needs without modifying the core code. Customizations can be done using tools like Oracle JDeveloper and Oracle ADF.
