Interview Prompt

A document management system needs to organize strings by their initial character for efficient lookup. Given a list of strings, return a dictionary where each key is a lowercase first character and the value is a list of all strings starting with that character, preserving original order within each group.

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
