Interview Prompt

We have a disk-usage listing, `entries`, where each line is a 'filepath size_bytes timestamp' string. Return the total bytes per file extension as a dict keyed by extension.

Summary

File types and their disk footprint. One type dominates.

How This Interview Works

  1. Read the vague prompt (just like a real interview)
  2. Ask clarifying questions to the AI interviewer
  3. Write and run your Python against test cases
  4. Answer the interviewer's follow-up questions, then get a hire or no-hire decision
