Practice questions in Swiggy's style

Original ZorixOS questions written the way Swiggy interviews, so you rehearse the real format. Not claimed as asked at Swiggy.

  1. Imagine Swiggy's delivery fleet is experiencing a 20% increase in average delivery time in a specific city due to a sudden surge in demand and road closures. Design a system to dynamically re-route drivers and optimize batching to mitigate this. Consider real-time traffic data, driver location, order priority, and restaurant prep times.

    Software EngineerSystem DesignTests: Evaluates the candidate's ability to design scalable, real-time systems for complex logistical challenges, incorporating various data sources and constraints.

  2. You are building a feature for Swiggy to allow users to pre-order groceries for delivery at a specific future time. Design the database schema to store these pre-orders, considering potential concurrency issues when multiple users try to book the same time slot for popular items. How would you handle inventory management for these pre-orders?

    Software EngineerDatabase Design & ConcurrencyTests: Assesses understanding of database schema design, ACID properties, and handling concurrent operations in a high-traffic e-commerce environment.

  3. A critical Swiggy service responsible for order assignment is experiencing intermittent high latency, causing delayed order fulfillment. You suspect a recent code deployment. How would you approach debugging this issue in a production environment with millions of concurrent orders? What metrics would you monitor?

    Software EngineerDebugging & Production MonitoringTests: Tests systematic debugging skills, knowledge of production monitoring tools, and ability to identify root causes of performance issues under pressure.

  4. Swiggy is considering launching a subscription service for premium grocery delivery, offering faster delivery and exclusive discounts. Design the API endpoints required to manage user subscriptions, including sign-up, renewal, cancellation, and integration with payment gateways.

    Software EngineerAPI DesignTests: Evaluates the candidate's ability to design robust and efficient APIs for a new product offering, considering security and scalability.

  5. Write a Python function that takes a list of Swiggy orders (each with restaurant ID, customer ID, delivery time, and order value) and returns the top 5 customers by total order value for a given restaurant.

    Software EngineerCoding & AlgorithmsTests: Assesses basic Python programming skills, data manipulation, and handling of list/dictionary operations.

  6. Design a rate limiter for Swiggy's restaurant API to prevent abuse and ensure fair usage. Consider different strategies like token bucket and leaky bucket, and discuss trade-offs in terms of accuracy, complexity, and resource consumption.

    Software EngineerSystem Design & ScalabilityTests: Examines understanding of distributed system principles, specifically rate limiting, and the ability to choose appropriate algorithms for a given scale.
