100 Adobe Developer Interview Questions & Answers

  1. What are your experiences with Adobe Experience Manager (AEM)?

    • Answer: I have [Number] years of experience working with AEM, focusing on [Specific areas like development, deployment, or specific AEM versions]. My experience includes developing custom components, workflows, templates, and integrating with other Adobe products like Adobe Analytics and Adobe Target. I'm proficient in using Sling models, OSGi bundles, and the AEM content repository. I understand the importance of performance optimization and have experience troubleshooting and resolving common AEM issues.

  2. Explain the difference between a Sling Model and a Sightly component.

    • Answer: A Sling Model is a POJO (Plain Old Java Object) that's annotated to expose data to a template. It's responsible for fetching and preparing data. A Sightly component (HTL) is a template that uses the data exposed by the Sling Model to render the user interface. Essentially, the Sling Model is the backend data provider, and Sightly is the frontend presentation layer. They work together to create a clean separation of concerns.

  3. How do you handle version control in an AEM project?

    • Answer: We typically use Git for version control in AEM projects. The code (OSGi bundles, Sling Models, Sightly components) is stored in a Git repository. We employ branching strategies, such as Gitflow, to manage different features and bug fixes. We carefully manage the JCR content repository, often using tools and strategies to track changes and merge content effectively. We also leverage tools that allow for comparing and merging JCR content.

  4. Describe your experience with AEM workflows.

    • Answer: I have experience designing, implementing, and troubleshooting AEM workflows. I understand how to use different workflow types, such as approval workflows, and configure various workflow steps and participants. I know how to integrate workflows with custom code to automate processes and improve efficiency. I'm also familiar with using workflow listeners and custom actions to extend workflow functionality.

  5. How do you optimize AEM performance?

    • Answer: AEM performance optimization involves several strategies. I focus on efficient query design for the content repository, minimizing the use of expensive queries and leveraging indexes. I optimize the code for my custom components and bundles, paying attention to resource usage and avoiding unnecessary computations. I utilize caching mechanisms effectively and understand the importance of proper content authoring practices. Proper image optimization and content chunking also contribute to better performance.

  6. Explain your understanding of the AEM architecture.

    • Answer: AEM's architecture is based on a modular design. It utilizes the Apache Sling framework, which provides a web application framework built on top of a JCR (Java Content Repository) for content storage. The architecture involves OSGi bundles for extensibility, a dispatcher for caching and load balancing, and various services for content management, personalization, and search. I understand the roles of different components like the publish instance, author instance, and dispatcher.

  7. How familiar are you with AEM DAM (Digital Asset Management)?

    • Answer: I'm familiar with AEM DAM and have experience [Describe your experience, e.g., working with assets, metadata, custom asset workflows, asset rendition generation, asset sharing/distribution]. I understand its functionalities in relation to asset organization, version control, and metadata management.

  8. What are your experiences with integrating AEM with other systems?

    • Answer: I have experience integrating AEM with [List systems, e.g., CRM, ERP, marketing automation platforms] using various methods like REST APIs, webhooks, and custom connectors. I understand the complexities involved in data mapping and synchronization across systems.
