  1. Imagine Cleartrip's flight booking system experiences a sudden surge in traffic during a flash sale. Describe how you would architect a solution to handle this load, focusing on database scaling, caching strategies, and load balancing. What are the potential bottlenecks and how would you mitigate them?

    Software EngineerSystem DesignTests: Evaluates system design and scalability thinking under pressure.

  2. A user reports that their flight search results are inconsistent, sometimes showing different prices or availability than before. Walk me through your debugging process to identify the root cause, considering factors like caching layers, concurrent requests, and external API integrations with airlines. What tools would you use?

    Software EngineerDebuggingTests: Assesses problem-solving and debugging skills in a live system.

  3. You're tasked with designing a new feature for Cleartrip that allows users to compare hotel prices across different booking platforms. What are the key technical challenges in integrating with external hotel APIs, ensuring data consistency, and displaying the information efficiently to the user?

    Software EngineerSystem DesignTests: Probes technical design choices for new features.

  4. Write a Python function to find the shortest flight route between two cities given a list of available flights, where each flight has a source, destination, and price. Assume a simplified scenario where price is the primary factor for shortest route. Discuss time and space complexity.

    Software EngineerCodingTests: Tests algorithmic thinking and coding proficiency.

  5. Cleartrip is considering optimizing its search algorithm to prioritize deals and personalized recommendations. How would you approach building a recommendation engine for flight and hotel bookings? What data would you use, and what machine learning models might be suitable?

    Software EngineerSystem DesignTests: Evaluates understanding of ML system design and implementation.

  6. You've identified a performance issue where loading the hotel details page takes longer than expected. How would you instrument the code to identify the specific components causing the delay? Discuss potential areas like database queries, image loading, and third-party script execution.

    Software EngineerDebuggingTests: Checks ability to diagnose performance bottlenecks.
