Interview Prompt

The log ingestion pipeline is choking on malformed IP addresses that slip through upstream validation. The warehouse team needs a filter that catches the bad ones before they hit the database. Given a string, determine whether it's a valid IPv4 address.

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
