Practice questions in Grab's style

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

  1. Imagine a user is trying to book a GrabFood order but encounters a 'Payment Failed' error. Walk me through how you would debug this issue on the backend, considering potential failure points in the payment gateway integration, order service, and notification system.

    Software EngineerDebuggingTests: Evaluates debugging skills and understanding of distributed systems.

  2. Design a system to handle real-time driver-passenger matching for GrabCar. Consider factors like driver availability, passenger demand, route optimization, and latency.

    Software EngineerSystem DesignTests: Evaluates system design capabilities and ability to handle scale and real-time constraints.

  3. You're tasked with optimizing the search ranking algorithm for GrabMart grocery items. How would you approach this? What features would you consider, and how would you evaluate the effectiveness of your changes?

    Software EngineerAlgorithm DesignTests: Evaluates algorithmic thinking and understanding of search relevance.

  4. Describe how you would implement a feature to allow users to split the fare for a GrabRide. Consider edge cases like partial payments and disputes.

    Software EngineerFeature ImplementationTests: Evaluates understanding of feature development and handling of complex logic.

  5. Write a Python function to calculate the estimated delivery time for a GrabFood order, given the restaurant preparation time, driver travel time, and potential traffic delays. Assume you have access to relevant APIs for traffic data.

    Software EngineerCodingTests: Evaluates coding proficiency and ability to model real-world scenarios.

  6. How would you design a rate limiter for the Grab user authentication API to prevent abuse and ensure availability?

    Software EngineerSystem DesignTests: Evaluates understanding of distributed systems and API security.
