Collaboration with Development Teams on Quality Issues Questions
Be prepared to discuss how you work with developers when reporting bugs, verifying fixes, and discussing quality improvements. Explain how you communicate effectively with non-QA team members, ask clarifying questions about expected behavior, and work together to ensure quality standards are met. Share an example of a time you collaborated with a developer to understand a complex issue or verify a fix.

Provide a concrete example of a bug report message (short text and structured fields) for a subtle regression: after a feature change, precision for a critical positive class dropped significantly. Include reproduction steps, metrics before/after, experiment IDs, potential root causes to suspect, and suggested next steps for the developer and data scientist.

Your training pipeline produces non-deterministic model artifacts across runs despite identical code and data. Describe how you would collaborate with engineers to root cause and eliminate nondeterminism, including what configuration flags, library settings, and tooling you would check and what reproducibility checks you would add to CI.

You're at a cross-functional postmortem for a model incident. List the first three concrete contributions you would make as an ML engineer to keep the meeting focused and ensure the outcome drives action (be explicit about artifacts, owners, and follow-up).

List and describe three simple, fast automated tests you would add to the CI pipeline (using Python and pytest) that validate a model's basic correctness on every commit. For each test include purpose, input shape/format, expected assertion, and why it helps catch regressions early.

Design an alerting and on-call triage process for ML quality issues (data drift, sudden metric regression, inference latency spikes) that spans ML engineers and developers. Define alert thresholds, ownership handoffs, contents of a runbook for each alert, steps to reduce false positives, and how to coordinate post-incident follow-ups.
