Interview Prompt

A URL shortening service needs to generate a short code from a full URL and store the mapping for later lookup. Given a URL string and a mutable code-to-URL dictionary, generate a 6-character short code using MD5 hashing and store the mapping. Return the short code.

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
