Problem Solving Behaviors and Decision Making Questions
Covers the interpersonal and cognitive traits that shape how a candidate solves problems, including initiative, ownership, proactivity, resilience, creativity, continuous learning, and evaluating trade offs. Interviewers probe when a candidate takes initiative versus seeks help, how they balance speed versus quality, how they persist through setbacks, how they generate creative alternatives, and how they learn from outcomes. This topic assesses mindset, judgment, and the ability to make principled decisions under uncertainty.

Design monitoring signals and SLOs for a global image classification model used in a mobile app. Consider per-region distribution shifts, latency targets, label-lag for human verification, confidence calibration, appeal/undo rates as user trust signals, and instrumentation needed to detect issues and trigger automated alerts. Describe what you'd monitor and why.

Describe a time you convinced a skeptical product or business stakeholder to accept an ML trade-off (for example, lower accuracy in exchange for faster inference or simpler system design). Explain how you structured the conversation, what evidence you presented (data, cost-benefit), and how you ensured alignment and a rollback plan after the decision.

You discover a strong correlation between a top predictive feature and a protected attribute (e.g., ZIP code correlating with race). Removing the feature substantially reduces model performance. How would you approach deciding whether to keep, remove, or transform the feature? Include technical mitigation options (causal analysis, fairness-aware training, adversarial debiasing), legal/ethical considerations, and how you'd present the recommendation to stakeholders.

In the context of machine learning engineering, how do you define 'ownership' of a model, pipeline, or feature? Describe concrete criteria or signals you use to decide when to escalate a problem to teammates or managers versus taking action yourself. Provide examples of thresholds, impacts, and communication practices you follow.
