Interview Prompt

Our load testing framework uses Fibonacci-spaced intervals for retry backoff. Write a function called fibonacci that takes an integer n and returns the first n Fibonacci numbers (starting with 0, 1). Use an iterative approach - no recursion, since this runs in a hot loop.

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
