I applied online. The process took 2 months. I interviewed at CVS Health in Jan 2024
Interview
I applied in Dec 2023 and starting interview process in January. The interview proceeds took about 2 months. Talked to 8 people in total. First was recruiter screening and then a coding interview with Senior DS involving basic pandas data manipulation and SQL in coderpad. Talked to the hiring manager after. Later 2 interviews were scheduled on the same day regarding A/B testing and business case review. Then the last 3 rounds were with senior leaders comprising of behavioral + resume based questions. The process is smooth although very long.
Interview questions [1]
Question 1
How would you go about measuring the effect of promotion strategy on CVS retail items.
The phone screen was surprisingly in-depth, lasting about 40 minutes and focusing heavily on real-world applications of data science. We discussed model development, particularly for predicting hospital readmissions, which was quite challenging. I had just practiced a similar scenario on PracHub that mirrored this section almost flawlessly. Following this, I went through a technical round where I tackled questions on feature engineering and demographic fairness. Ultimately, I received an offer but decided to decline it after weighing my options.

Question 1
How would you build a model to predict 30-day hospital readmission risk for chronic patients? Walk through your feature engineering using claims and prescription data, model selection tradeoffs (logistic regression vs gradient boosting given explainability requirements for healthcare), how you'd handle class imbalance (around 10% readmission rate), and how you'd evaluate fairness across demographic groups before deployment.
