This question evaluates a candidate's ability to design and articulate end-to-end system architecture, including components, data flow, scalability, reliability, security, observability, and operational trade-offs, thereby assessing architectural thinking, system ownership, and technical justification skills.

Provide a deep dive on one production project you owned or co-built. Assume the audience has not seen your system before. You may anonymize proprietary details. ASCII diagrams are acceptable.
Tip: Be concrete with APIs, schemas, and SLOs; highlight the risks you mitigated and the ones you consciously accepted.
