AI and Machine Learning Background Questions
A synopsis of applied artificial intelligence and machine learning experience including models, frameworks, and pipelines used, datasets and scale, production deployment experience, evaluation metrics, and measurable business outcomes. Candidates should describe specific projects, roles played, research versus production distinctions, and technical choices and trade offs.

Explain the difference between model training and model inference in production. In your answer describe compute and storage needs, latency expectations, data pipelines, monitoring/observability, and how requirements differ for batch training vs low-latency online inference. Give a concrete example (e.g., fraud detection or recommendation).

Explain the key differences between research (experimental) ML work and production ML from a Solutions Architect's perspective. Focus on reproducibility, data quality and lineage, performance guarantees, scalability, monitoring needs, and how teams need to shift responsibilities when moving from prototype to production. Provide examples of common pitfalls.

A customer trains large Transformer models weekly on a 50TB dataset. As a Solutions Architect, outline strategies to reduce cloud training cost while maintaining model quality: using spot/preemptible instances, mixed-precision training, gradient checkpointing, data sharding strategies, selective dataset sampling, and controlled hyperparameter search. Discuss the trade-offs for each.

Design a multi-region inference architecture for an image classification API serving global users with 10M requests/day, <100ms P95 latency, and GDPR-compliant data residency requirements. Describe data flows, model synchronization approach, handling of stale models, consistency models, caching strategy, and rollback procedures across regions.

A client requests an ethical-AI roadmap before deploying a hiring recommendation model. As a Solutions Architect, outline a practical roadmap covering bias assessment and dataset audits, representative data collection, fairness metrics selection, mitigation strategies (re-weighting, adversarial debiasing, post-processing), human oversight and escalation, documentation, and legal/compliance checks and vendor assessments.
