Swiggy's system-design rounds are built on real-time logistics at dinner-peak scale: assign orders to nearby delivery partners with low latency, stream live location and ETA to customers, and serve a personalised restaurant-discovery feed.
In 2026 strong candidates reach for geospatial indexing and batching for the assignment problem, separate the write-heavy location-ping path from ETA reads, and handle the demand spike during peak hours. Interviewers push on freshness of menu availability, ranking signals, and cache invalidation. Generic 'store it in a database and scale horizontally' answers get taken apart by the follow-ups.
