web-crawler Interview Questions

Featured in Atlassian system design interviews, this architecture challenge focuses on building a distributed web crawler tailored for discovering image assets. Candidates must design APIs for job submission and status tracking while addressing data persistence, recursive link traversal, and failure management at scale. This exercise evaluates large-scale system planning and asynchronous processing skills. Access to the comprehensive design guide and expert architecture breakdown requires a subscription.

This Lyft system design interview examines your ability to architect a massive web harvesting and archiving infrastructure powered by distributed worker nodes. It assesses core concepts like URL frontier management, politeness rate limiting, deduplication, and fault-tolerant scheduling at web scale. You will design components that ensure continuous synchronization of millions of documents. Access to the complete architectural blueprint and detailed solution guide requires a subscription.

Prepare for high-pressure system design rounds with this Salesforce onsite hands-on mini project, which requires building a concurrent web scraper under tight time constraints. You will need to demonstrate live coding proficiency, manage asynchronous requests, process and sort data according to strict criteria, and generate CSV exports while clearly narrating your thought process.
