I applied online. The process took 2 weeks. I interviewed at CVS Health (Woonsocket, RI) in Feb 2017
Interview
Contacted by a recruiter. I was asked to complete a SQL Test on Hirevue. There are 5 questions, which were easy to me. The recruiter got back saying the test was good, and the Director wanted me to talk with a Sr. Manager on another phone. The second interview turned out to be a disaster. The Sr. Manager didn't seem well as he coughed and talked like his voice was via his nose. I asked if he was ok. It was very difficult to catch his words to understand what he was saying. After his introduction I didn't understand and asked him to repeat, but still didn't understand his words. Much guessing for words during the interview. Asked to rate my predictive modeling skills as well as some others. A previous project was picked up to discuss, which wasn't a predictive model but an heuristic optimization model. Some questions to ask to walk him through from data processing to create the model. I explained the way the model was created with data from a database, how we preprocessed data, of course not the way data would be preprocessed for a predictive model, how the constraints were created via matrix operations. Doesn't seem the explanation was understood. I told him that the model was an optimization model so the way to pre-process data wasn't like a predictive model. Overall it was incredibly challenging to understand the interviewer's words, and I believe there was disconnection or misunderstanding in the communication during the interview. It was my mistake not to tell the problem right away and ask for rescheduling.
Interview questions [1]
Question 1
SQLdata cube, special join, SQL operators like IN. Pick a previous project, walk through the steps.
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.
Interview questions [1]
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.
Easy Chill, comfortable, wasnt difficult, more on health and pharmacy stuff,
Interview was friednly and accommodating, overall i would say good experince, the process was smooth, But applied with out reffereal
I applied online. I interviewed at CVS Health in Mar 2026
Interview
Interestingly, the first round was with AVP, and he discussed many mathematical concepts.. The second and third rounds were on the same day, for coding and case study. One week later was VP interview with behaviors.
