Imagine a user reports that their grocery order is consistently showing as delivered 10 minutes before the actual delivery time on the Blinkit app. How would you debug this issue, considering potential causes from the delivery executive's app to the backend order status service?
Software EngineerDebugging Distributed SystemsTests: Assesses ability to debug complex, distributed systems and think about edge cases in a real-time delivery scenario.Blinkit's rider app needs to display the most optimal route for multiple deliveries. Design a system that can efficiently calculate and update these routes in real-time, considering traffic, delivery windows, and rider availability. What are the key components and potential bottlenecks?
Software EngineerSystem Design Real-time RoutingTests: Evaluates system design skills for real-time, location-based services at scale.We're seeing an increase in reported 'missing item' complaints. Write a SQL query to identify delivery executives who have a disproportionately high rate of missing item complaints compared to their delivery volume, considering orders with multiple items versus single items.
Software EngineerSQL Query Optimization & AnalysisTests: Tests SQL proficiency and the ability to analyze data for operational issues.Design a service to handle fluctuating real-time inventory updates for thousands of SKUs across multiple dark stores. Consider the trade-offs between data consistency, latency, and system throughput.
Software EngineerSystem Design Scalable Data ManagementTests: Assesses system design capabilities for high-throughput, real-time data synchronization.A surge in user sign-ups is overloading our recommendation engine, leading to stale recommendations. How would you architect a scalable recommendation system that can handle sudden traffic spikes while maintaining personalization quality?
Software EngineerSystem Design Scalable Recommendation EngineTests: Evaluates understanding of scaling machine learning systems and handling traffic variability.Write a function to calculate the estimated delivery time for an order. Consider factors like current order volume, rider availability in the vicinity, and average travel time from the dark store. Discuss the edge cases and how you would handle them.
Software EngineerAlgorithm Design EstimationTests: Tests algorithmic thinking and practical application for a core business metric.
