To succeed at Omada Health, you need to perform consistently across several core evaluation areas. Understanding what interviewers look for in each of these domains will help you structure your preparation effectively.

Experimentation & Causal Inference

Because Omada Health operates in the healthcare space, establishing clinical and operational efficacy is paramount. You will be evaluated on your ability to design robust experiments and draw valid conclusions from observational data when traditional A/B testing is not possible.

Be ready to go over:

• A/B Testing Frameworks – Designing randomized experiments, calculating sample sizes, and determining statistical power.
• Causal Inference Techniques – Applying propensity score matching, difference-in-differences, and instrumental variables to observational datasets.
• Hypothesis Testing – Choosing the correct statistical tests and interpreting p-values, confidence intervals, and effect sizes.
• Advanced concepts (less common) – Multi-armed bandits, synthetic controls, and sequential testing methods.

Example scenarios:

• "How would you measure the impact of a new digital coaching program when patients are allowed to opt in or out of the program themselves?"
• "Design an experiment to test whether sending push notifications at different times of day improves patient log-in rates."

Machine Learning & Predictive Modeling

You will be assessed on your ability to build, evaluate, and deploy machine learning models that solve real-world healthcare and operational problems. This includes everything from initial exploratory data analysis to selecting the appropriate modeling techniques and evaluation metrics.

Be ready to go over:

• Exploratory Data Analysis (EDA) – Identifying data patterns, handling missing clinical values, and detecting outliers.
• Supervised Learning – Implementing classification and regression models, such as random forests, gradient boosting, and logistic regression.
• Model Evaluation – Selecting metrics like ROC-AUC, precision-recall, and F1-score based on business and clinical constraints.
• Advanced concepts (less common) – Time-series forecasting, survival analysis for patient retention, and natural language processing for coach-patient chat logs.

Example scenarios:

• "Walk me through how you would build a model to predict which patients are at high risk of dropping out of the program within their first 30 days."
• "How would you handle a forecasting problem where historical clinical data is highly seasonal and impacted by external healthcare trends?"

Product Sense & Stakeholder Collaboration

Data science at Omada Health does not exist in a vacuum. You must demonstrate strong product intuition and the ability to work effectively with product managers, operations teams, and clinical leaders to turn data into actionable insights.

Be ready to go over:

• Metric Definition – Defining clear, measurable key performance indicators (KPIs) for new features or clinical programs.
• Prioritization – Balancing technical debt, model improvement, and new feature requests from stakeholders.
• Data Storytelling – Translating complex statistical results into clear business recommendations.

Example scenarios:

• "If the product team wants to launch a feature that your models suggest will have minimal impact on patient outcomes, how would you handle that conversation?"
• "What dashboard or metrics would you build for operations managers to help them monitor coach workloads and patient satisfaction?"

As a Data Scientist at Omada Health, your day-to-day work will be highly collaborative and dynamic. You will work closely with product managers, engineers, clinical designers, and operations specialists to drive data-informed decision-making across the organization.
