AEM Interview Questions PDF

AEM, Interview Prep

When you are preparing for technical interview, it is sometimes beneficial to know what types of questions that may be asked during your interview.

Instead of having to have you read through multiple posts, I figured it would be beneficial if all of the questions were located in one place.

So, I decided to create a PDF version of all the interview questions and answers that I have previously posted.

Inside the document, you will find a table of contents that lists all of the questions, and what page they are located on in the PDF. Also, for each question there are references to where you can read more information on the topic.

Here are some more AEM interview questions that could come up during a technical interview:


Q: Why is a Content Management System (CMS) required?

A: A content management system is a piece of software that is used to create and manage documents and Web sites. Many websites are dynamic, so their content needs to be updated frequently. In order manage these changes efficiently, it is recommend that a content management system be used. Which is why AEM is a content management system.


Q: What is RESTful?

A: Representational State Transfer (REST) is an architectural style and an approach to communications that is often used in the development of web services. It relies on a stateless, client server, cacheable communications protocol. RESTful applications use HTTP requests to post data, read data, and delete data.


The six architectural constraints of REST are: uniform interface, stateless, cacheable, client server, layered system, and code on demand.

Q: What are the benefits of using OSGI?

A: The main benefits of using OSGI are:
  • It reduces the complexity of the system by having everything in bundles.
  • It makes the components loosely coupled and easy to manage since they can be installed, deleted, updated, started, and stopped at run time.
  • It increases the performance of the system since parts of the application that are not in use, do not need to be loaded in the memory.

Q: What is the listener property in AEM?


A: The listener property in AEM for a component is used to define what happens before or after an action on the component. This is added by using the “cq:listeners” node with a node type of “cq:EditListenersConfig”.

The listener property can also be added to any widget in AEM. In order to add a listener to that widget you just need to add to add a node that is called “listeners” with a type of “nt:unstructured”. Then you just need to add child nodes to the “listeners” node that are events of that widget. You can find a list of events for each widget by searching CQ Widget API documentation.

Q: How do you load digital assets in dam?


A: You can add digital assets to your dam by using the graphical user interface or through WebDav access. If you are using the graphical user interface, you would just browse for the selected files you would like to add, and then cq will create the metadata for those assets in the dam folder. You would generally use the WebDav option when you want to upload a large number or assets at once.

When you are preparing for technical interview, it is sometimes beneficial to know what types of questions that may be asked during your interview. I am going to list some questions that may be asked during an AEM interview, and the answers to these questions. This is not a definitive guide by any means, but a way to get going in the right direction.

This is part one of my AEM interview questions. You find the other parts here:

Q: What is AEM?

A: Adobe Experience Manager (AEM), is a java based content management system that is offered from Adobe. It was previously called Day CQ5, but was acquired from Adobe in 2010. AEM is based on a content repository and uses the JCR to access the content in the repository. AEM uses the Apache Sling framework to map request url to the corresponding node in the content repository. It also uses the OSGI framework to internally allow modular application development.

Q: What are the advantages of AEM over another CMS?

A: One big advantage of AEM over another CMS is how it integrates with other products from Adobe and with the Adobe Marketing Cloud. AEM comes built in with features like workflows to control content in the CMS, the use of search queries to find anything you are looking for, setting up social collaboration, tagging content, and a way to manage your digital content.
