Differentiating an MVP from a throwaway prototype

This tests your ability to balance speed and long-term viability. Differentiate by intent: an MVP is the first version of a product, meant to evolve, while a prototype is disposable. A great answer introduces Minimum Viable Architecture (MVA)—building just enough structure to support future needs without over-engineering. A red flag is advocating for a 'sacrificial architecture' without understanding the massive risk and cost of the inevitable rewrite.
