Practice questions in Anthropic's style
Original ZorixOS questions written the way Anthropic interviews, so you rehearse the real format. Not claimed as asked at Anthropic.
Imagine you are designing a new feature for Claude that allows users to upload documents and ask questions about their content. Describe the system architecture, considering potential scale and latency requirements. How would you handle large document uploads and efficient retrieval of information for answering queries?
Software EngineerSystem DesignTests: Evaluates system design capabilities, scalability considerations, and understanding of distributed systems.Claude occasionally generates responses that are factually incorrect or hallucinate. Describe a process for detecting and mitigating these failure modes in a production environment. What metrics would you track to quantify the quality of Claude's factual accuracy?
Software EngineerDebugging and ReliabilityTests: Assesses debugging skills, understanding of failure modes, and pragmatic approaches to quality control.A user reports that Claude is not understanding the nuance in their prompts, leading to off-topic or unhelpful responses. Walk me through how you would debug this issue. What components of the Claude system might be involved, and what steps would you take to diagnose the root cause?
Software EngineerDebuggingTests: Tests debugging methodology and the ability to reason about complex software systems.Describe how you would implement rate limiting for Claude's API to prevent abuse and ensure fair usage for all customers. Consider different strategies (e.g., per user, per API key, per IP address) and their tradeoffs.
Software EngineerAPI Design and ScalabilityTests: Probes understanding of API design principles and practical considerations for managing service load.You need to build a feature that allows Claude to access and process real-time information from the internet. Discuss the technical challenges and potential solutions. How would you ensure the information is current and relevant?
Software EngineerSystem DesignTests: Evaluates the ability to design for dynamic and real-time data processing in a large-scale system.Write a SQL query to find the top 5 users who have submitted the most feedback on Claude's responses in the last month, along with the count of their feedback submissions.
Data ScientistSQLTests: Measures proficiency in SQL for data extraction and basic aggregation.
