Interview Prompt
Our upstream sensor export arrives as a `data` list that mixes plain numbers, the same numbers written as strings, and the occasional batch of readings wrapped in its own inner list. Turn it into one flat list of every reading scaled by `multiplier`.
Summary
The upstream API has no idea what a schema is.
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
