Walk me through how you would design and train a model for a production use case from scratch.

Strong candidates cover data sourcing and cleaning, feature engineering, model selection rationale, training/validation strategy, and deployment considerations — not just the algorithm. Look for awareness of compute cost and latency tradeoffs.

How do you handle model drift and ensure ongoing performance in production?

Look for monitoring strategies: data drift detection, prediction distribution tracking, retraining triggers, and A/B evaluation. Engineers who only describe training but not post-deployment lifecycle signal limited production experience.

Describe your experience with LLMs and prompt engineering or fine-tuning.

Mature AI Engineers distinguish between prompt engineering, RAG pipelines, and full fine-tuning — and know when each is appropriate. Look for hands-on experience with OpenAI, Anthropic, or open-source models via Hugging Face.

What MLOps practices do you follow when deploying and versioning models?

Strong answers reference experiment tracking (MLflow, W&B), model registries, CI/CD pipelines for ML, containerization (Docker/Kubernetes), and rollback strategies. This separates research-oriented engineers from those who can own production systems.

How do you approach bias, fairness, and explainability in your models?

Look for specific tools and frameworks: SHAP, LIME, or model cards. Engineers working in regulated industries (finance, healthcare) should demonstrate awareness of audit requirements and disparate impact testing — not just theoretical knowledge.

How have you worked with non-technical stakeholders to define an AI use case and measure its success?

Top AI Engineers translate business problems into ML problem formulations and define success metrics that go beyond accuracy — precision/recall tradeoffs, business KPIs, and ROI framing. Candidates who can only talk technically signal limited cross-functional experience.
