This question evaluates your understanding of mobile application architecture and your ability to make informed decisions based on best practices and project requirements.
How to answer
- Start with a brief overview of the application and its purpose
- Detail your role in the architecture design process
- Discuss the key architectural patterns you considered (e.g., MVVM, MVP, etc.)
- Explain considerations like performance, scalability, and user experience
- Mention any technologies or frameworks you utilized and why
What not to say

Sample answer
“At my internship at a local startup, I contributed to the architecture of a fitness tracking app. I advocated for the MVVM pattern to enhance testability and maintainability. Key considerations included ensuring smooth performance during data updates and implementing a responsive UI. We used Firebase for real-time data synchronization, which greatly improved user experience. This experience taught me the importance of balancing technical choices with user needs.”
