Interview Prompt

You are given a list where each element can be a number, a string that looks like a number, a list of numbers, or None. Your job is to extract every numeric value - converting string representations along the way and discarding nulls - apply a multiplier to each, and return the results as a sorted flat list of floats.

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
