Technology
Your collaborative document app needs to work offline on planes, in subways, and in rural areas, then sync seamlessly when connectivity returns. Multiple users may edit the same document offline.
The brief
Solve it in plain text with any AI you like, in about 10 to 20 minutes. A judge scores how you reasoned, not whether you matched an answer.
CRDTs solve conflict-free merging but have large metadata overhead. OT (Operational Transform) requires a central server. Last-write-wins loses data. Figma uses a custom CRDT variant. Google Docs uses OT. Neither works well offline for extended periods.
