Interview Prompt

Our distributed index stores sorted data across shards that may be rotated at an unknown pivot. Write a function called search_rotated that finds a target in such a rotated sorted array in O(log n) time, returning its index or -1 if absent.

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
