Design Dropbox

Design Dropbox — A Staff playbook focused on chunked upload strategies, delta sync algorithms, conflict resolution for files, and client-side dedup ownership — not just S3 wrapper tutorials.

This playbook is part of the full calibration library.

Staff interviews are decided on nuance — tradeoff framing, ownership boundaries, and failure anticipation. This playbook covers the depth that separates Senior from Staff+.
