Tests prioritization under pressure across multiple projects, including trade-off judgment, stakeholder communication, and ownership of outcomes.
Tests influence without authority: aligning stakeholders through data, empathy, and ownership to drive a decision and measurable outcome.
Tests how you handle ambiguity while maintaining accuracy, documentation discipline, and ownership of the final output.
Tests whether you can translate technical complexity into clear, audience-appropriate documentation that drives understanding and action.
Design an LLM serving system that balances latency, cost, scalability, and safety for production traffic.
Explain a practical approach to fine-tuning an LLM for a specific task, including data, evaluation, and hallucination risks.
Pick the right metrics to evaluate a machine learning model and explain why they fit the problem.
Compare RAG and fine-tuning, and decide when each is the better fit for an LLM product.
