After submitting the assessment, the interviewers reviewed my implementation in detail. One of the main things they asked me about was the design decisions I made, particularly around: How I handled authentication and authorization, and why I chose a specific approach (e.g., JWT vs. session-based, role hierarchy). My microservice setup, especially how I structured inter-service communication and ensured decoupling. Security considerations, such as how I protected file uploads and prevented common vulnerabilities. They were especially interested in understanding my reasoning behind certain architectural choices and how I ensured scalability and maintainability.
