Program Level System Design Questions

Approaches system design from a program and delivery perspective. Candidates should explain how they clarify requirements and constraints up front, decompose complex systems into deliverable components and milestones, and plan schedules that account for technical complexity and dependencies. Describe how to involve and align engineering teams on architecture decisions, translate technical trade offs for stakeholders, identify and mitigate risks, set acceptance criteria, and plan for capacity, testing, deployment, and operational readiness. Include how program planning accounts for cross team coordination, technical debt, release coordination, and measurement of success.

Your program has a strict budget cap but traffic is projected to grow threefold in the next two quarters. Propose a program-level plan that balances cost and latency trade-offs across training and serving. Include short-term mitigations (for example: caching, model compression), medium-term architectural changes, timeline, priority of actions, risk assessment, and a stakeholder communication plan.

Describe what 'program-level system design' means for machine learning initiatives. Explain how it differs from a single-model technical design and list the typical responsibilities, artifacts, and stakeholders you would expect a program lead to produce (for example: roadmap, milestones, acceptance gates, dependency matrix, runbooks, and stakeholder communication plan).

Two teams are in conflict: the Platform team wants to freeze infra changes for stability to meet SLAs, while the Product team needs infra changes to improve model accuracy. As the program lead, describe the decision framework you would use to balance stability and product needs, temporary mitigations you might authorize, how you would document the decision, and how to communicate it to both teams and executives.

Design a gated rollout plan for a high-risk ML model subject to fairness and regulatory constraints (for example: credit scoring or medical triage). Include offline fairness checks, pre-release independent audits, staged rollouts with subgroup performance monitoring, explicit approval gates, logging and evidence for auditors, and post-release remediation workflows.

Explain the difference between model-level acceptance criteria (for example: precision/recall thresholds, fairness checks, generalization tests) and program-level acceptance criteria (for example: deployment readiness, operational SLOs, business KPI lift). Provide examples of how a failing model-level test should or should not block a program-level gate.
