I applied online. The process took 2 weeks. I interviewed at CVS Health (Providence, RI) in Mar 2022
Interview
One short technical interview in the first round, then 3 consecutive interviews in the second round. The second round included another technical interview that was harder than the first one.
Interview questions [1]
Question 1
How would evaluate model performance when you have an imbalanced data set?
First you must complete a Hirevue with basic behavioral questions. It includes questions like why do you want to work for CVS. It also asks questions about teamwork and problem resolution.
Very straightforward interview, make sure you know basic ML conceptual questions like classifiers and A/B testing, etc. A few questions about Pandas and SQL like how would you remove missing values, etc.
Hirevue with basic behavioral questions followed by a technical conversation with Senior Data Scientist. No live coding, relatively easy. Prepare questions like why CVS and basic SQL, Pandas, Statistical Concepts. Be prepared to walk through a past project.
