Interview Prompt

A UI analytics team needs to count the distinct navigation paths a user can take through a fixed-length flow. Given n steps in a sequence, a user can advance 1 or 2 steps at a time. Return the total number of distinct ways to reach step n from step 0.

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
