Common WordPress interview questions cover the difference between pages and posts, themes and plugins, what hooks (actions and filters) are, how to create a custom post type, how to make a site faster and more secure, how to debug errors with WP_DEBUG, how WooCommerce works, child themes, and how you would handle a broken site under pressure. Expect a practical task, such as fixing a layout or building a small feature.
- Know the core concepts clearly and simply.
- Prepare examples from your own projects.

How do you prepare for the practical test?
Picture an interview task: “This Elementor page is broken on mobile and the contact form sends nothing. You have 45 minutes.” Candidates who calmly take a backup, check responsive settings, inspect the console and set up SMTP stand out, even if they do not finish everything. Practise with the guides on responsive editing, critical errors and hooks and filters.
