• "Walk me through how you would prepare a highly imbalanced dataset for a machine learning model designed to detect fraudulent claims."

Business Scenarios & Stakeholder Management

A great analyst does more than write code; they solve business problems. This area evaluates your ability to handle ambiguity and communicate with leadership.

Be ready to go over:

• Requirements Gathering – How you translate vague business requests into concrete technical requirements.
• Prioritization – Managing competing demands from multiple clinical and business stakeholders.
• Data Translation – Presenting complex analytical findings to senior directors who may not have a technical background.

Example scenarios:

• "A business director asks for a metric that you know is misleading due to underlying data quality issues. How do you handle this conversation?"
• "Describe a time when you had to deliver an analytical project with incomplete data. What assumptions did you make, and how did you validate them?"
