6 OIC Interview Questions With Sample Answers

You can review the following common OIC interview questions along with sample answers to help you prepare for an interview:

1. What is Oracle Integration Cloud Service?

Interviewers often ask this question to test your understanding and experience with the Oracle Integration Cloud Service. You can start by explaining what Oracle Integration Cloud Service is and follow that with the uses of the integration platform. In your answer, mention how the platform can benefit customers.

Example: 'Oracle Integration Cloud Service (ICS) is Oracle's cloud-based integration platform as a service (iPaaS). You can use it to easily and securely integrate and connect your applications in the cloud. The platform features an intuitive integration designer that is web-based and which you can use for point-and-click integration between applications.

With its feature-rich dashboard, you can monitor transactions and gain real-time insights about them. Along with featuring an intuitive user interface, it offers an extensive software as a service (SaaS) Adapters library. By making it easier to connect between applications, the ICS can help customers connect their on-premise applications and cloud-based applications.'

2. What do you know about application integration with ICS?

You may encounter this question during interviews for developer and cloud architect roles as employers require candidates to know application integration. Explain what application integration is and its benefits briefly. You can also mention a few of its key features in your answer.

Example: 'Application integration with Oracle Integration Cloud Service (ICS) involves connecting SaaS and on-premise applications in the cloud. As the ICS platform offers embedded best practices, a visual application builder, process automation with drag-and-drop design and pre-built integration flows, you can integrate applications quickly and with end-to-end visibility. You can use machine learning recommendations for mapping data.

You can simplify integration and connect with any application, service or data store with pre-built application adapters. These include CX adapters, database adapters, enterprise messaging adapters, enterprise resource adapters and supply chain management (ERP/SCM) adapters, human capital management (HCM) adapters, industries adapters, productivity and social adapters, robotic process automation (RPA) adapters, service-oriented infrastructure (SOA) adapters and technology adapters.'

3. What is the difference between ICS and OIC?

By understanding the difference between ICS and OIC, you can decide which iPaaS suits your purpose. When interviewers ask this question, you can give a brief definition of ICS and OIC. You can also mention their features in your answer.

Example: 'Integration Cloud Service (ICS) and Oracle Integration Cloud (OIC) are both cloud-based integration platform as a service offerings from Oracle. The company released ICS in 2015 and has replaced it with OIC, which has more features and offers more services. With ICS, you can easily build integration in the cloud and connect to on-premise and cloud-based applications and services. Oracle manages the overall infrastructure, which includes cloud management, backup, restore and patching.

With OIC, the customer is responsible for managing the infrastructure. Its PaaS components include ICS, Oracle Process Cloud Service (PCS) and Oracle Visual Builder Cloud Service (VBCS). Process cloud service (PCS) is a cloud-based process automation tool that you can use for designing, automating and managing business processes. Oracle Visual Builder Cloud Service (VBCS) is a cloud-based tool that requires little or no coding knowledge. You can use it for creating and deploying web and mobile applications from the browser.'

4. Can you explain the security capabilities in Oracle Integration Cloud?

Cloud security is an important concern for businesses that use cloud-based platforms and applications. You can expect this question when interviewing for a developer, cloud architect or related role. You can explain the security approach for protecting data on-premises and in the cloud.

Example: 'With OIC, you can use various security features to connect applications and technologies securely. For example, with the REST adapter, you can select an inbound authentication scheme. You can use OAuth to connect to applications with Fusion Apps adapters. When you use file transfer protocol (FTP) adapters, you can connect to these servers using an implicit security sockets layer (SSL) connection. OIC allows available-to-promise (ATP) serverless integration. For databases that are privately hosted, you can use wallet-based authentication. If you host SSH file transfer protocol (SFTP) servers privately, you can avail message payload security capabilities.'

5. Can you explain the use of lookups in Oracle Integration Cloud?

Interviewers ask this question during job interviews, as you may use lookups to map values and carry out integrations in the Oracle Integration Cloud. In your answer, you can provide a brief definition of a lookup and explain the use of lookups. Try to include an example in your answer.

Example: 'Lists of values in applications are called lookups. A static list of values that contains lookup codes is a lookup type. The lookup type also contains the translated meaning of each code in it and an optional tag. When end users see the lookup type, they see the list of translated code meanings and understand the available values for an object. Only valid values appear on a list and there are no duplicate values.

Lookups provide a means of validation by associating values that one application uses for a specific field to values that other applications use in the same field. For example, when representing a country, a source application uses a country code and a target application uses a country name. With lookups, it is possible to maintain this mapping and use it for integration during runtime.'

6. Can you explain what a package is in OIC?

As packages make it convenient to import and export integrations from OIC services, interviewers may test your technical knowledge by asking this question during a job interview. You can answer by giving a brief definition of a package. You can explain how it is useful for importing and exporting integrations.

Example: 'When you create an integration in OIC, you group it into a single structure that is known as a package. You can use a single package to group one or more integrations. You can export the package from the source instance and import it into the target instance. When that happens, all the integrations that the package contains get automatically imported with it.'

Tips To Prepare For Your Oracle Integration Cloud Interview

The following tips may help you improve your chances of success in a job interview for an Oracle Integration Cloud position:

Research the company and the Oracle Integration Cloud role

You can get relevant information from the company's website, social media platforms, industry reports, news stories, professional networking sites and other online sites. You can visit the social media and professional networking profiles of engineers and cloud architects working for the company and learn about the projects on which they have worked. That can help you understand the work the company does and focus on getting better informed about it before your interview.

Improve your technical knowledge of Oracle Integration Cloud

Interviewers may ask you various technical questions to test your knowledge of working with OIC. They may ask about integrating on-premise and cloud applications, automating end-to-end processes, generating automatic mapping and centralising management. You may also get questions about handling security policy details and error handling capabilities. Even if you have extensive experience working with OIC, it is advisable to refresh your technical knowledge, especially in areas relevant to the open position.

Build Oracle Integration Cloud experience

If you are new to the field or do not have extensive work experience, you can build your OIC knowledge from informative tutorials, articles and videos on Oracle Cloud and other online sites. Learn as much as you can about automating business processes, using integrations to connect applications and using the visual builder to develop applications. Practise creating OIC Instance.

Conduct mock interviews

Find out about the company's interview process and ask a friend, family member or colleague to conduct mock interviews similar to it. Ask for their feedback on your performance. You can also video record the mock interview and review your articulation level, tone and posture. This can help you make necessary improvements and make a good impression during the interview successfully.
