Interview Prompt

Our text normalization pipeline replaces domain-specific jargon with standardized root words. Write a function called replace_words that takes a list of root words and a sentence - for each word in the sentence, if any root is a prefix, replace with the shortest matching root. Return the modified sentence.

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
