Practice questions in GEICO's style

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

  1. Imagine GEICO's mobile app has a feature where users can file claims by uploading photos and videos. Describe how you would design the backend system to handle the upload, storage, and initial processing of these media files, considering millions of users and varying network conditions. What technologies would you consider and why?

    Software EngineerSystem DesignTests: Evaluating the candidate's ability to design scalable, fault-tolerant systems for media handling in a high-traffic consumer application.

  2. A critical component of GEICO's website experiences intermittent latency spikes, impacting user login and quote generation. How would you approach debugging this issue? What tools and techniques would you use to pinpoint the root cause, considering potential bottlenecks in microservices, databases, or network infrastructure?

    Software EngineerDebuggingTests: Assessing problem-solving skills and systematic debugging approaches for complex, distributed systems.

  3. GEICO's quote engine is a complex system that calculates insurance premiums. If tasked with optimizing the performance of this engine, what are the first few code optimizations you would investigate? Discuss potential algorithmic improvements or data structure choices that could reduce computation time.

    Software EngineerCoding ReasoningTests: Gauging the candidate's understanding of performance optimization at the code level and their ability to reason about algorithmic efficiency.

  4. Consider GEICO's online quoting process. How would you design a system to detect and mitigate potential bot traffic attempting to scrape quote data or submit fraudulent applications, while ensuring legitimate users have a seamless experience?

    Software EngineerSystem DesignTests: Testing the candidate's ability to design security measures and traffic management solutions for a high-volume web application.

  5. GEICO's 'Gabi' acquisition aimed to bring personalized insurance shopping. If you were building a new recommendation engine for users looking to switch providers, how would you model user preferences and policy data? What are the key metrics for success?

    Software EngineerMachine Learning/Recommendation SystemsTests: Evaluating understanding of building and scaling recommendation systems, including data modeling and performance metrics.

  6. Describe a scenario where you had to refactor a large, existing codebase at GEICO. What was your approach to ensuring code quality, maintainability, and backward compatibility throughout the process?

    Software EngineerCoding ReasoningTests: Assessing experience with code quality, maintainability, and the practical challenges of refactoring in a large organization.
