Competency-based questions focus on assessing specific skills, behaviors, and experiences relevant to the role of a Power Platform developer. Here's a list of competency-based questions you might encounter in a Power Platform developer interview:
Technical Skills and Knowledge:
1. Can you describe your experience with building Power Apps applications? What types of apps have you built? Answer: "Certainly. I have extensive experience developing Power Apps applications to address various business needs. Some of the apps I've built include: Data entry and tracking apps for inventory management. Customer relationship management (CRM) apps to streamline sales processes. Incident reporting and management apps for workplace safety. Survey and feedback collection apps for market research. Each app was tailored to the specific requirements of the organization, utilizing Power Apps' intuitive design interface and integration capabilities."
2. How do you approach designing user interfaces in Power Apps to ensure a positive user experience? Answer: "When designing user interfaces in Power Apps, I follow a user-centered approach focused on simplicity, intuitiveness, and consistency. I start by understanding the users' needs and workflows through stakeholder interviews and user research. Then, I design clean and visually appealing layouts with easy navigation using standard controls and responsive design principles. I prioritize accessibility and ensure that the UI is optimized for different devices and screen sizes. Regular user testing and feedback sessions help refine the UI to ensure a positive and seamless user experience."
3.Can you explain the differences between canvas apps and model-driven apps in Power Apps?
Answer: "Certainly. Canvas apps and model-driven apps are two types of applications that can be built using Power Apps.
Canvas apps: These are highly customizable apps where you start with a blank canvas and design the user interface using drag-and-drop controls. Canvas apps are suitable for scenarios requiring flexibility and customizability, such as creating ad-hoc applications or integrating with multiple data sources.
Model-driven apps: These apps are built on top of the Common Data Service (CDS) and are driven by data models. The user interface is generated automatically based on the data schema, providing a standardized and consistent user experience. Model-driven apps are ideal for scenarios where data consistency and scalability are priorities, such as building CRM or HR management systems."
4.How do you connect Power Apps to external data sources? Can you give examples of data sources you've integrated with?
Answer: "Power Apps provides seamless integration with various external data sources, enabling us to build powerful applications that leverage existing data. I typically connect Power Apps to external data sources using built-in connectors or custom connectors. Some examples of data sources I've integrated with include:
SharePoint Online for document management and collaboration.
Microsoft SQL Server for relational databases and structured data.
Microsoft Dynamics 365 for CRM and business process automation.
Microsoft Excel for spreadsheet data analysis and reporting.
Custom APIs for integrating with third-party systems and services."

Integrate data from different systems by automating data synchronization and data entry tasks.
Trigger notifications and alerts based on predefined conditions or events.
Implement scheduled tasks such as data backups, report generation, and system maintenance.
Power Automate's intuitive visual designer and extensive library of connectors have enabled me to automate repetitive tasks and improve operational efficiency across organizations."
6.Have you worked with Power BI? Can you discuss your experience with creating reports and dashboards?
Answer: "Yes, I have worked extensively with Power BI to create interactive reports and dashboards that provide actionable insights to stakeholders. My experience includes:
