Interview Prompt
A room-booking service holds a day's calendar as `meetings`, a list of `[start, end]` intervals. Return the fewest rooms that can host all of them without two live meetings sharing a room.
Summary
Every booking needs a room. Find the busiest moment.
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
