Interview Prompt

Some of our identifier columns are stored in reverse order for suffix-index lookups. Write a function that reverses a string and returns it. The input is guaranteed to be a non-None string.

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
