Practice questions in Poshmark's style

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

  1. Imagine Poshmark has a sudden spike in user-generated content (photos, descriptions) that is taking too long to process and display. Describe your debugging process to identify the bottleneck. What specific Poshmark features might be involved?

    Software EngineerDebuggingTests: Evaluates debugging methodology and understanding of how Poshmark's core features interact with backend systems.

  2. Poshmark wants to implement a feature allowing users to bundle multiple items from different sellers into a single purchase. Design the API endpoints and database schema changes required to support this. Consider potential race conditions when multiple users try to bundle the same items simultaneously.

    Software EngineerSystem DesignTests: Assesses system design skills, API design, database schema modeling, and awareness of concurrency issues at scale.

  3. Poshmark's recommendation engine shows a user a list of recommended items. How would you design an A/B test to evaluate a new algorithm that prioritizes items from sellers the user has previously interacted with (liked, commented, or purchased from)? What are the key metrics to track?

    Software EngineerCoding Reasoning / A/B TestingTests: Tests logical reasoning, ability to translate product ideas into testable code/logic, and understanding of A/B testing principles.

  4. Describe a situation where you had to optimize a piece of code for performance in a large-scale application. Relate it to a potential Poshmark scenario, such as optimizing the loading of a user's closet or the search results page.

    Software EngineerCoding Reasoning / PerformanceTests: Evaluates problem-solving skills and practical experience with performance optimization in a real-world context.

  5. Poshmark is experiencing an increase in fraudulent listings. How would you design a system to detect and flag potentially fraudulent items before they are widely viewed? Consider data sources and machine learning approaches.

    Software EngineerSystem Design / SecurityTests: Assesses system design capabilities, understanding of security concerns, and application of ML for fraud detection at scale.

  6. Design a system to handle real-time notifications for Poshmark users, such as when an item they liked receives an offer or is sold. Consider scalability, reliability, and different notification channels (push, email).

    Software EngineerSystem DesignTests: Evaluates design of scalable, real-time systems and understanding of distributed systems concepts.
