🔍 Power Pages Interview Questions

Hello developers 👨‍💻👩‍💻,

If you're preparing for an interview and Microsoft Power Pages is part of the stack, you're in the right place. In this blog, I'm sharing some commonly asked Power Pages interview questions, along with a bit of practical context wherever possible.

These questions aren't just theoretical — they come from my real-world experience working with Power Pages projects and from interviews I’ve recently attended or conducted.

📌 Quick Refresher: What is Power Pages?

Power Pages is a secure, low-code platform used to create websites that can be accessed externally (by customers, vendors, partners, etc.). It’s built on top of Dataverse and tightly integrated with the Power Platform ecosystem — like Power Automate, Power Apps, Power BI, and more.

It’s especially useful for scenarios where you need external users to interact with business data — like registrations, service requests, or knowledge bases.

💬 Most Common Power Pages Interview Questions

1. What is the difference between Power Pages and Power Apps (Canvas/Model-Driven)?

This is a classic question.

Power Pages is for building external-facing websites.
Canvas apps are best for custom UI apps used internally.
Model-driven apps are used when you need form and data-driven logic inside the organization.

👉 Real-world tip: Mention how Power Pages is useful when users outside your Azure AD need access.

2. How is security managed in Power Pages?

Security in Power Pages is handled using:

Web Roles (controls what a user can see/do)
Table Permissions
Authentication providers (Azure AD, Microsoft, LinkedIn, etc.)
Dataverse security model

Pro tip: Bring up row-level security via Table Permissions — many forget that.

3. How do you connect Power Pages with other Microsoft services?

You can integrate Power Pages with:

Power Automate (e.g., workflows on form submission)
Power BI (embed dashboards)
Dataverse (core data model)
Custom APIs (via Web Templates or Liquid)

It’s a plus if you mention embedding a chatbot using Copilot Studio.

4. What are Web Roles, and how do they differ from security roles in Dataverse?

Web Roles are for Power Pages only — they define permissions at the site level.
Dataverse Security Roles are used inside model-driven apps or Dataverse directly.

Some people confuse both — knowing the difference gives you an edge.

5. Can you customize the UI of Power Pages?

Yes! Power Pages allows full HTML, CSS, and JavaScript customization. You can also:

Use Bootstrap themes
Add custom JavaScript/jQuery
Modify using Visual Studio Code (via Power Pages design studio preview)

6. How do you enable authentication in Power Pages?

Authentication options include:

Azure AD
Microsoft Accounts
LinkedIn
Local authentication (via Email and password)

You manage these from the Power Pages admin center under Site Settings → Identity Providers.

7. What is the role of Web Templates and Page Templates?

Web Templates: Used to define reusable HTML/logic using Liquid templating.
Page Templates: Blueprint for creating content pages.

If you’ve worked with Liquid (used in Shopify too), that’s a great thing to mention.

8. How do you troubleshoot issues in Power Pages?

Key tools:

Browser Dev Tools for UI issues
Portal Checker in Maker Portal
Tracing logs (for server-side errors)
Dataverse logs (for data-related errors)

Real-world example helps: Share how you fixed a page not loading because of missing table permission.

9. Can we trigger Power Automate flow from Power Pages?

Yes! You can:

Use a form’s submission to trigger flow
Call HTTP-triggered flows using JavaScript
Use Power Automate cloud flows for backend automation

10. What are some limitations of Power Pages?

Be honest here:

Custom coding is limited compared to traditional web dev
Not ideal for real-time heavy data scenarios
Licensing cost may be a barrier for small businesses

✍ Final Tips Before Your Interview

Always back your answers with real project examples if possible.
Interviewers like to hear how you used Power Pages, not just definitions.
Be familiar with Dataverse, Power Automate, and basic Liquid scripting.
