I applied online. The process took 4 weeks. I interviewed at CVS Health in Nov 2023
Interview
I had a digital interview that asked standard behavioral questions and then a 45 min technical interview that had questions on Python, SQL, some stats, and some ML. Just got the notification of the final round which is supposed to be two interviews, one technical and one problem solving/business acumen.
Interview questions [1]
Question 1
What's difference between mutable and immutable data types?
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.
