Interview Prompt

Our embedded analytics module can't use Python built-ins due to sandbox restrictions. Write a function called find_max that takes a list of integers and returns the largest value without using max(). Return None for empty lists.

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
