Landing a role as a Dynamics 365 Developer means proving your technical expertise, problem-solving mindset, and stakeholder management skills. If you’re preparing for interviews, here are some of the most common and important questions you should be ready to answer.
Common D365 Developer Questions
Q. What are the limitations of Dynamics?
A. For example, a plugin has a 2-minute timeout. Other limits include API throttling and data query restrictions. See more limits here.
Q. How would you consume an external API and where would you store the API key?
A. Use a backend service (C#, Node.js, or Python) and store keys in Azure Key Vault, not directly in PowerApps where they could be exposed.
Q. What is a Modern Business Unit?
A. A way to partition users into separate business areas while still allowing access to shared data across units. Learn more here.
Q. How would you quality check your code?
A. Use SaaS scanning tools like Veracode or SonarQube for static analysis, code smells, and CVE detection.
Q. What is a CVE?
A Common Vulnerability and Exposure. Often discussed in the finance sector, these are publicly known security risks you must mitigate in your code.
Q. How strong are your stakeholder management skills? Can you deliver bad news and challenge requirements?
A. Communication is key. Employers look for developers who can push back constructively and explain trade-offs clearly.
Technical Areas You’ll Be Tested On
Expect technical questions around the following areas:
- Testing: Selenium and Microsoft Playwright
- Data modeling approaches: No-code, low-code, pro-code
- Automation with Power Automate, Event Hub, SharePoint
- Custom development: Plugins, workflows, SDK vs OData vs FetchXML
- CI/CD pipelines for Dynamics and Power Apps solutions
- Environment strategy: Dev, Test, PreProd, Prod
- Security: Business Units, Teams, Roles, Permissions
- Secrets management in Power Automate
- Many-to-many relationships in Power Automate
- Query expressions in Dynamics plugins
Shift Left Culture
Interviewers often ask about shift left testing. This means moving testing earlier in the development lifecycle instead of leaving it until the end. The benefits include:
- Early bug detection and cheaper fixes
- Improved quality from the start
- Faster feedback loops for developers
- Reduced rework in later stages
Practices like test-driven development (TDD), continuous integration (CI), and behavior-driven development (BDD) support shift left testing.
More Advanced Questions You May Encounter
- What are NFRs and how do they apply to Dynamics?
- Managed vs unmanaged solutions, and best practices
- How to rollback a solution deployment and its impact on data
- Methods for integrating Dynamics with external systems
- When to use plugins and their limitations
- How to create multiple records at once efficiently
- Automated testing with Playwright or Selenium
- How to structure solutions across environments
- Working with many-to-many relationships
- CI/CD pipelines for deployment
Final Thoughts
Dynamics 365 interviews test more than just technical knowledge. They assess whether you can write secure, maintainable code, handle enterprise-scale deployments, communicate effectively with stakeholders, and embrace modern DevOps and testing practices. If you can confidently answer these questions, you will be well-prepared to succeed in your interview.
