Data Science Challenge & Presentation

This is one of the most critical phases of the evaluation. You will be given a take-home assignment based on a public dataset (such as data.gov) to solve independently. You will then bring your code and findings to the onsite interview to present to the team.

Be ready to go over:

• Code Quality & Structure – Writing clean, well-documented, and reproducible code (typically in Python or R).
• Analytical Methodology – Explaining why you chose specific data cleaning techniques, feature engineering steps, or modeling approaches.
• Data Storytelling – Translating raw outputs into a compelling, logical narrative that non-technical stakeholders can easily follow.
• Advanced concepts (less common) – Handling massive scale, optimizing pipeline execution times, and implementing advanced dimensionality reduction techniques.

Example scenarios:

• "Walk us through your approach to cleaning the missing demographic fields in the public healthcare dataset."
• "Why did you choose this specific machine learning model over simpler baseline alternatives for this challenge?"

Technical Fundamentals & Whiteboarding

During the onsite, you will face live technical sessions involving whiteboarding and conceptual problem-solving. These interviews assess your raw engineering and statistical capabilities.

Be ready to go over:

• SQL & Query Optimization – Demonstrating your ability to manipulate complex databases, perform joins, window functions, and aggregations.
• Statistical Inference – Understanding hypothesis testing, A/B testing design, confidence intervals, and experimental setup.
• Machine Learning Algorithms – Explaining the mechanics, assumptions, and limitations of standard models (e.g., random forests, regression, clustering).

Example scenarios:

• "Write a SQL query to identify the top 10% of doctors who have the highest volume of specific procedures within a state."
• "Explain how you would design an experiment to test whether a new cost-estimator UI layout changes user conversion rates."

Data Product Design & Product Sense

This interview evaluates your ability to think like a product owner. Amino's data science team does not just build models; they help define what the product actually is.

Be ready to go over:

• Feature Definition – Identifying what data inputs are necessary to build a specific user-facing feature.
• Metric Design – Creating robust, mathematically sound metrics to represent complex concepts like "doctor experience" or "cost efficiency."
• User Empathy – Understanding how users interact with data and ensuring that model outputs are actionable and easy to understand.

Example scenarios:

• "How would you design an algorithm to rank search results for doctors when a user searches for 'knee replacement'?"
• "If our cost estimates are occasionally inaccurate due to insurance volatility, how should we communicate that uncertainty to the user?"

As a Data Scientist at Amino, your daily work will span across multiple domains, requiring you to be highly adaptable and collaborative.

You will be responsible for querying, cleaning, and modeling massive healthcare datasets, such as insurance claims databases and provider registries.
