Interview Prompt
For a character-level profile of a raw text field, report how often each character of `text` appears as `[char, count]` pairs. The counting lives in a `CharFrequency` class whose `get_counts()` returns those pairs, which `char_frequency(text)` builds and returns.
Summary
Every character has a count to answer for.
How This Interview Works
- Read the vague prompt (just like a real interview)
- Ask clarifying questions to the AI interviewer
- Write and run your Python against test cases
- Answer the interviewer's follow-up questions, then get a hire or no-hire decision
