Global media ingest
Design a globally-distributed media ingest system for a short-video app where creators worldwide upload from mobile and the uploaded video must become available to a global audience fast, regardless of where the creator is. A creator in Jakarta uploading to a US-region origin gets terrible throughput and slow first-publish. You must minimize upload latency and first-byte-to-published time while keeping a coherent global view of content. Design the edge ingest, the path from edge to processing, and the consistency model.
What a strong answer looks like
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.
