Anthropic SWE Loop

This course contains a growing collection of past and recently asked Anthropic SWE (Software Engineering) coding and system design interview questions. Anthropic interviews often focus on practical problems (less on LeetCode-style puzzles), and they care about your thought process and how production-ready your code is. Speed and correctness are of course relevant as well.

Use this course to work through Anthropic-style questions such as designing a single-threaded or concurrent web crawler, and more, including system design questions to give yourself the best chance to land the offer. Each problem reflects the style, difficulty, and reasoning depth you should expect in the Anthropic software engineering coding interview loop.
