Interview Prompt
You're consolidating playback sessions from a streaming service's event logs, where each session in `intervals` is a `[start, end]` timestamp pair. Collapse every run of overlapping sessions into one continuous span.
Summary
Overlapping sessions. One clean line.
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
