Ho presentato la mia candidatura online. La procedura ha richiesto 4 settimane. Ho sostenuto un colloquio presso CVS Health nel mese di mar 2024
Colloquio
I had a total of one take home assessment and 4 rounds interview.
Take home assessment: MCQs on Stats, Probability, basic ML
Round 1: Live Coding round on Coderpad
SQL questions - can be between 2-5 questions testing on CTEs, joins, window functions, CASE When
Python - Data Manipulation and Data wrangling, basic list comprehensions
ML questions: Basic ML questions on Random Forests, classification, outlier detection
Rounds 2-4: Managerial rounds (Each of the managers can take one round at a time or all together can take one round and finalize)
This round is a mix of everything.
ML questions - Depends on the role, but I was asked mostly traditional ML
Behavioral questions
Case Based Scenarios
Resume based questions and follow up cross questions
Number of case based questions in each category depends on the manager. In one round I had 1 case based, in two other rounds, I had 2 case studies in another round I had 4 case studies. Can't say the exact number.
And if they ask one type of questions more, then other type of questions will be less.
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.

Domanda 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

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.
