Interview Prompt
A log collector hands you a buffer where each slot is either a single event id or a batch of ids grouped in a nested list. Return every id from `items` in one flat list.
Summary
Some arrive alone, some in batches. Line them all up.
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
