• Advanced concepts (less common) – Recursive CTEs, query plan analysis, and partition strategies for massive healthcare datasets.

Example questions:

• "Write a query to find the rolling 30-day readmission rate for patients diagnosed with a specific chronic condition."
• "How would you design a database schema to support a new real-time provider search feature while keeping query latency under 100 milliseconds?"

Operational Forecasting & Case Studies

The case study is a central component of the Oscar Health interview loop. It typically involves an Excel-based exercise where you must forecast operational resources, such as man-hours and financial budgets.

Be ready to go over:

• Resource allocation modeling – Structuring Excel sheets to forecast operational capacity, staffing needs, and dollar spend based on historical volume.
• Assumption validation – Clearly defining and defending the assumptions, growth rates, and seasonal trends built into your models.
• Sensitivity analysis – Explaining how changes in key variables (e.g., a sudden 15% spike in claims volume) impact your final forecast.

Example scenarios:

• "Build a 12-month forecast for the SIU team to determine how many analysts are needed to handle an expected increase in fraud referrals, keeping in mind the onboarding ramp-up time for new hires."
• "Present an Excel model that projects the operational cost savings of automating 30% of manual provider data updates."

Strategic Discussion & Opinion Formulation

In this round, you will be presented with an ambiguous topic or business dilemma. You must quickly formulate a logical opinion, back it up with structured reasoning, and defend your stance against constructive pushback from the interviewer.

Be ready to go over:

• Structured opinion building – Developing a clear thesis and supporting it with data points, risk assessments, and operational trade-offs.
• Handling pushback – Remaining calm and analytical when interviewers challenge your assumptions or present counter-arguments.
• Strategic trade-offs – Evaluating the pros and cons of different analytical approaches (e.g., building a complex predictive model vs. utilizing a simple heuristic).

Example scenarios:

• "The company is deciding whether to build an in-house provider data validation tool or purchase a third-party vendor solution. Formulate a recommendation and defend your position."
• "Should we prioritize reducing the rate of false-positive fraud alerts in our SIU pipeline, or should we focus on catching every possible instance of fraud, even if it increases manual review times? Defend your choice."

As a Data Analyst at Oscar Health, your day-to-day responsibilities will vary depending on your specific team alignment, but they will center around driving operational efficiency, ensuring compliance, and delivering strategic insights.
