  1. Imagine Booking.com experiences a sudden surge in bookings for a popular European city due to a last-minute event. Describe how you would design a system to handle the increased load on the search and booking APIs, ensuring low latency and high availability. What are the key bottlenecks you anticipate?

    Software EngineerSystem DesignTests: Evaluates ability to design scalable systems under high load and identify potential failure points.

  2. A user reports that sometimes, after clicking 'book', they get an error page instead of a confirmation, but the booking did go through. Debug this scenario. What tools and techniques would you use to pinpoint the root cause in a distributed system?

    Software EngineerDebuggingTests: Assesses problem-solving skills and familiarity with debugging distributed systems.

  3. Booking.com is considering offering dynamic pricing for hotels based on real-time demand and competitor pricing. Discuss the architectural changes and technical challenges involved in implementing such a feature. How would you ensure data consistency and prevent race conditions?

    Software EngineerSystem DesignTests: Tests understanding of distributed systems, concurrency, and real-time data processing.

  4. You notice a significant increase in latency for hotel searches originating from mobile devices in the last week. Outline your approach to diagnose and resolve this issue. What metrics would you monitor, and what potential causes would you investigate?

    Software EngineerDebuggingTests: Probes diagnostic skills and ability to troubleshoot performance issues in a production environment.

  5. Booking.com's search results page displays numerous hotels with varying availability and prices. How would you design the data structures and caching strategies to efficiently serve these search results to millions of users concurrently, considering that hotel data can change frequently?

    Software EngineerSystem DesignTests: Evaluates knowledge of data structures, caching, and performance optimization for large-scale applications.

  6. You are tasked with building a feature that recommends alternative accommodations to users who have searched for a specific hotel but it's unavailable. How would you approach the technical implementation, considering factors like user preferences, location, and price range?

    Software EngineerCoding/ReasoningTests: Assesses coding logic, algorithm design, and understanding of recommendation system components.
