Demonstrate leadership and ensure data compliance
Overview
This question evaluates leadership, program execution, stakeholder management, risk and tradeoff reasoning in machine learning engineering, along with expertise in data privacy, regulatory compliance, and operational data governance for user-data-driven systems.
Behavioral & Leadership: Leading Through Reorg While Shipping ML + Ensuring Data Compliance
Context
You are the ML lead during a reorganization that reshapes team structure and dependencies. You must continue delivering on an existing ML roadmap while ensuring end-to-end data compliance for user-data-driven ML systems at scale.
Part A — Reorg and Roadmap Execution
Tell a STAR-style story (Situation, Task, Actions, Results) about a time you led a team through a reorganization while still shipping on an ML roadmap. Specifically cover:
- Realigning scope
- Resetting timelines and risk management
- Stakeholder management (PM, Eng, Legal/Privacy, Infra, adjacent product teams)
- Maintaining team morale and psychological safety
- Key tradeoffs you made (with rationale)
- Metrics you used to judge success (product impact, delivery reliability, cost, quality, team health)
Provide specific incidents, decisions, and measurable outcomes.
Part B — Data Compliance for ML Using User Data
Walk through how you ensure compliance in ML pipelines that use user data. Address each of the following:
- Identifying and minimizing PII
- Consent and purpose limitation
- Regionalization and data residency (e.g., GDPR/CCPA/CPRA)
- Retention and deletion policies
- DSAR workflows (access/erasure/portability)
- Audit logging and access controls
- DLP/redaction
- Sandboxing for experimentation
- Vendor/data-sharing reviews
- Data lineage and documentation
- Preventing sensitive data leakage in training and evaluation
Provide specific incidents, decisions, and measurable outcomes.
