Original Summary

On LeetCode you write one function, it passes, and you&#x27;re done. Most AI labs such as Anthropic and OpenAI, as well as some big tech companies such as Meta, Snowflake and Databricks, don&#x27;t stop in one function and instead ask multi-step questions that are closer to real-world problems.<p>Say you&#x27;re building a key-value store. Step 1 is get, set, delete, count. Once your tests pass, Step 2 unlocks: expiring keys. Then nested transactions. Then atomic batches.<p>I built this because I couldn&#x27;t find a good place to practice for multi-step, multi-file questions. The questions are based on ones people have reported from those loops.<p>Check it out at <a href="https:&#x2F;&#x2F;loopprep.dev" rel="nofollow">https:&#x2F;&#x2F;loopprep.dev</a>.<p>There are 24 questions, 3 free, and no signup to try them.<p>Happy to answer questions.
