Interview Prompt

The infra team suspects certain file types are hogging disk, but nobody has the numbers. Given file metadata strings ('filepath size_bytes timestamp'), calculate total storage per file extension. Files without extensions go under 'no_ext'. Treat extensions as case-insensitive.

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 python solution with real code execution
  4. Get instant feedback and a hire/no-hire decision
