Interview Prompt

Using functools.lru_cache(maxsize=None), define fib(n) recursively where fib(0) = 0, fib(1) = 1, else fib(n-1) + fib(n-2). Print fib(10) and fib(20), each on its own line.

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
