Interview Prompt
A monitoring service keeps event IDs in ascending order, but a wraparound in its ring buffer means the export `nums` comes back rotated. Given that array and a `target` ID, return the index where `target` sits.
Summary
Someone shuffled it. Now locate what you came 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
