Live streaming segment delivery
Design the content-delivery path for live sports streaming to millions of concurrent viewers with <10s glass-to-glass latency. The manifest updates every few seconds as new segments are produced, viewers are on varying bandwidth, and a goal-moment causes a synchronized request spike for the same just-produced segment. Explain segment packaging, caching of live vs VOD content, and how you handle the synchronized stampede on each new segment.

Clarify scale and constraints first. Propose a clean component breakdown, then go deep on the hard parts (data model, bottlenecks, consistency, failure modes) and name the trade-offs you are making.

Which questions mattered is sealed until you submit. Telling you now would just be handing over the edge cases.
