Interview Prompt

We run a cloud file storage platform. Users upload files from multiple devices, organize them into folders, and share files with other users. We need to model the metadata for analytics: upload volume, storage consumption per user, sharing behavior, and quota enforcement. Design the data model.

Summary

A file is also a folder. A folder is also a file.

How This Interview Works

  1. Read the vague prompt (just like a real interview)
  2. Ask clarifying questions to the AI interviewer
  3. Write your data modeling solution with real code execution
  4. Get instant feedback and a hire/no-hire decision
