In this section, we’ll review the various interview questions that might be asked during a Data Scientist interview at Humana. The interview process will likely focus on your technical skills, experience with machine learning, and your ability to apply data-driven solutions in a healthcare context. Be prepared to discuss your past projects, the methodologies you used, and how you can contribute to Humana's mission of improving healthcare through AI and data science.
This question assesses your practical experience with statistical modeling and its application in real-world scenarios.
Discuss the specific model you built, the data you used, and the results it produced. Highlight how it influenced decision-making or improved outcomes.
“I developed a logistic regression model to predict patient readmission rates. By analyzing historical patient data, I identified key risk factors, which allowed the healthcare team to implement targeted interventions. This model reduced readmission rates by 15% over six months.”
This question evaluates your familiarity with industry-standard tools and frameworks.
Mention specific frameworks like Scikit-Learn, TensorFlow, or PyTorch, and provide examples of projects where you utilized them.
“I primarily use Scikit-Learn for classification tasks. In my last project, I implemented a random forest classifier to predict patient outcomes based on various health metrics, achieving an accuracy of 85%.”
This question tests your data manipulation skills and ability to work with databases.
Explain your proficiency in SQL, including specific queries or operations you’ve performed to extract and analyze data.
“I have extensive experience with SQL, particularly in writing complex queries to join multiple tables. For instance, I created a query that aggregated patient data from different sources to analyze treatment effectiveness, which helped inform our clinical strategies.”
This question focuses on your understanding of model validation and interpretability, which is crucial in healthcare.
Discuss techniques you use for model validation, such as cross-validation, and how you communicate model results to stakeholders.
“I use cross-validation to assess model performance and ensure it generalizes well to unseen data. Additionally, I employ SHAP values to explain model predictions, making it easier for stakeholders to understand the factors influencing outcomes.”
This question assesses your data wrangling skills, which are essential for any data scientist.
Describe the challenges you faced with the dataset and the steps you took to clean and prepare it for analysis.
“I worked with a large dataset containing patient records with missing values and inconsistencies. I implemented data imputation techniques for missing values and standardized formats across the dataset, which improved the quality of our analysis significantly.”
This question evaluates your understanding of feature engineering and its importance in model performance.
Explain the methods you use for feature selection and why they are important for model accuracy.
“I use techniques like recursive feature elimination and feature importance from tree-based models to select the most relevant features. This not only improves model performance but also reduces overfitting.”
This question assesses your problem-solving skills and resilience in the face of difficulties.
Share a specific challenge you encountered, the steps you took to address it, and the outcome.
“In a project predicting patient outcomes, I faced issues with imbalanced classes. I implemented SMOTE to oversample the minority class and adjusted the model’s threshold, which improved our recall rate by 20%.”
This question gauges your commitment to continuous learning in a rapidly evolving field.

Provide a brief overview of reinforcement learning and discuss how it can be applied in healthcare settings.
“Reinforcement learning involves training models to make decisions based on rewards. In healthcare, it can be used for personalized treatment plans, where the model learns to optimize patient outcomes based on feedback from previous treatments.”
This question assesses your awareness of potential challenges in machine learning implementations.
Discuss common issues such as overfitting, data leakage, and the importance of proper validation techniques.
“Common pitfalls include overfitting due to complex models and data leakage from improper training-test splits. To avoid these, I ensure to use cross-validation and maintain strict separation between training and testing datasets.”
