Interview Prompt

A data pipeline processes columnar reports that need to be pivoted for downstream consumption. Write a function that takes a 2D matrix and returns its transpose - rows and columns swapped. Return an empty list for empty input.

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
