Interview Prompt

We have a list of records, each one a dict, and the name of a field to look at. Return a dict mapping each value that field takes to how many records have it.

Summary

Some fields speak louder than others.

How This Interview Works

  1. Read the vague prompt (just like a real interview)
  2. Ask clarifying questions to the AI interviewer
  3. Write and run your Python against test cases
  4. Answer the interviewer's follow-up questions, then get a hire or no-hire decision
