Role Team and Infrastructure Questions Questions
Guides asking targeted questions about the specific role, team responsibilities, and the technical or operational infrastructure that supports the role. Topics include typical responsibilities, on call rotations or support models, current infrastructure challenges, tech stack or tooling, success metrics for the role, collaboration with adjacent teams, opportunities for growth, and infrastructure priorities. This helps candidates demonstrate role understanding and probe for operational and strategic expectations.

Describe the typical responsibilities of a machine learning engineer on a product-facing team. In your answer, compare and contrast tasks owned by ML engineers versus data scientists and ML researchers, give concrete examples of deliverables and operational duties (monitoring, retraining, incident handling), and propose an expected time split between development, production support, and cross-functional collaboration.

For large-scale distributed training across hundreds of GPUs, describe how you would design the training system including data sharding, distributed optimizer strategy, checkpointing, and fault tolerance. Discuss trade-offs between synchronous and asynchronous training and how to handle stragglers.

Design a career ladder for ML engineers on a growing team from junior to staff/principal. For each level define core competencies (technical, system design, mentoring, cross-team impact), typical milestones, and how promotions should be evaluated objectively. Explain how you would implement this ladder with engineering managers and HR.

Describe an ML production technology stack you have used. For each layer, explain the role of components such as data ingestion, feature store, orchestration, training framework (e.g., PyTorch/TensorFlow), artifact store, serving, monitoring, and infrastructure-as-code. Explain why each component mattered for reliability and developer velocity.
