How do you debug an issue you cannot reproduce locally?

Walk through logs, metrics, environment differences, recent changes, and how you would narrow the blast radius.

Describe a time you improved performance.

Name the bottleneck, the measurement method, the change you made, and the before-and-after result.

Balance correctness, readability, test coverage, and tone. Show that your review improves the work and the relationship.

Use incident structure: detection, mitigation, communication, root cause, and prevention.

Discuss user impact, risk, timeline, ownership, and whether the debt will slow future work.

Translate the engineering choice into user experience, cost, reliability, or delivery impact.

Cover naming, tests, small boundaries, clear contracts, and how future engineers will understand the change.

Show how you compared tradeoffs with evidence instead of making it about preference.

Mention running the app, reading tests, tracing one user flow, asking focused questions, and shipping a small change.
