Interview Prompt

A configuration loader overrides earlier settings with later ones, so when a list contains duplicates the last occurrence always wins. Write a function that takes a list and returns a new list with duplicates removed, keeping only the last occurrence of each value in original order.

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
