← Microsoft Interview Insights
I went straight to the customer-facing app and spent way too long on the ordering flow before they nudged me toward the backend.
Start by clarifying the scope and goals of the food truck system, then outline the high-level architecture covering both front-end and backend components. Focus on key user flows, data flow, and technical trade-offs, while aligning with business objectives and scalability.
Pro tip: Emphasize how your design decisions directly impact the user experience and business metrics, such as order accuracy and wait times, to demonstrate product thinking beyond technical implementation.
Ask questions to understand the target users, core features (e.g., menu browsing, ordering, payment, location tracking), and constraints like budget, timeline, and scale.
Map out the primary user journeys for customers and truck operators, and identify the necessary front-end interfaces (e.g., mobile app, web dashboard) and their key functionalities.
Outline the backend services (e.g., order management, payment processing, inventory, location services), database schema, and APIs needed to support the front-end and business logic.
Discuss choices like monolithic vs. microservices, real-time vs. batch processing, and how to handle peak loads, data consistency, and third-party integrations.
Recap the proposed system, highlight MVP features versus future enhancements, and explain how the design meets business goals and can evolve over time.
