  1. Avito users often complain about slow loading times for search results pages, especially in categories with many listings like 'Real Estate'. What factors could contribute to this and how would you investigate/resolve these performance bottlenecks from an engineering perspective?

    Software EngineerPerformance OptimizationTests: Evaluates understanding of web performance, debugging methodologies, and practical solutions for scaling high-traffic applications.

  2. Design a highly scalable and fault-tolerant system for real-time chat between buyers and sellers on Avito, considering millions of concurrent users, message delivery guarantees, and notification systems.

    Software EngineerSystem DesignTests: Assesses knowledge of distributed systems, real-time communication protocols, and handling high concurrency.

  3. Avito needs to optimize its listing search results to prioritize relevance based on multiple fuzzy criteria such as location proximity, price range, keywords, and seller reputation. Describe an algorithm or approach to combine these factors for ranking and discuss its computational complexity.

    Software EngineerCoding ReasoningTests: Evaluates algorithmic thinking, search relevance strategies, and understanding of data structures for efficient querying.

  4. A sudden and significant spike in failed payment transactions for promoted listings is reported. As a software engineer, outline your step-by-step debugging process to identify the root cause, considering Avito's microservices architecture and external payment gateways.

    Software EngineerDebuggingTests: Assesses systematic problem-solving skills, understanding of distributed system debugging, and API integration issues.

  5. How would you design the data model for Avito's item categorization system, which needs to support deeply nested categories (e.g., 'Electronics > Phones > Smartphones') and category-specific attributes (e.g., 'car mileage' for 'Autos' vs. 'number of rooms' for 'Real Estate')?

    Software EngineerData ModelingTests: Evaluates database design principles, flexibility for schema evolution, and handling diverse data structures.

  6. Avito wants to implement a robust recommendation engine for 'similar items' or 'items you might like' shown on a product page. Describe the architecture, data sources, and potential algorithms you would consider, focusing on cold-start problems for new listings.

    Software EngineerSystem DesignTests: Assesses understanding of recommendation systems, data pipelines, and strategies for handling sparse data.
