Dear readers, these Drupal Interview Questions have been designed specially to get you acquainted with the nature of questions you may encounter during your interview for the subject of Drupal. As per my experience good interviewers hardly plan to ask any particular question during your interview, normally questions start with some basic concept of the subject and later they continue based on further discussion and what you answer:

Drupal is a free and open source Content Management System (CMS) that allows organizing, managing and publishing your content.

Drupal is very powerful and can be used for building large, complex sites. It is PHP based template and allows non-technical users to add and edit the content without any HTML or Web design knowledge. Using Drupal CMS, it can be easy to interact with other sites or technologies and can handle complex forms and workflows. It is available with more than 16000 modules which can be addressed with Drupal core and add-on modules.
