Interview guidance: emphasize clarity, correctness, observability, and safe concurrency patterns.

• Always show timeouts and context handling for I/O.
• Use small, focused interfaces and avoid premature abstraction.
• Call out observability: logs, metrics, and traces when discussing production.
• Mention common pitfalls: map concurrency, loop variable capture, defer in loops.
