Interview Prompt

A shared room-booking calendar stores each reservation as a `[name, start, end]` record, and you need to flag every scheduling clash. Return the clashing pairs as `[name_a, name_b]`.

Summary

Two reservations, one slot. Find every clash.

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
