Our candidates report that CVS Pharmacy is less interested in polished theory than in whether you can make sense of messy, business-facing data under real constraints. The strongest signal across experiences is practical SQL fluency: joins, unions, window functions, multiple CTEs, and aggregation show up repeatedly, and one candidate described the SQL as getting difficult very quickly. We’ve also seen that the company can be inconsistent in how much structure it gives, so candidates who do best are the ones who can stay calm when the prompt is under-specified and still drive the problem forward.
A recurring theme is that CVS wants people who can connect analytics to healthcare operations. Multiple candidates mentioned questions about high-risk patients, claims data, lower-cost care steering, and experimentation, which tells us the team cares about whether you can translate a model or analysis into a member or cost outcome. The interviewers also seem to probe for domain judgment around healthcare data scale and messiness, not just textbook ML knowledge. One candidate specifically called out large EHR datasets, which is a good reminder that real-world data quality and volume matter here.
We’ve also noticed that the behavioral side is not just a formality. Several candidates were asked to explain their resume, favorite project, and why CVS, and the best responses were grounded in concrete work rather than generic motivation. At the same time, one experience felt surprisingly light on technical depth, so the signal can vary by interviewer. That inconsistency means candidates should be ready to make their value obvious from the first minute: clear background, crisp healthcare relevance, and a way of thinking that sounds useful to a business team, not just technically correct.

Synthesized from candidate reports. Individual experiences may vary.
A standard HR-style phone or video screen where the recruiter explains the role and asks about your background. Candidates were also asked about SQL and Python experience, visa status, location preference, availability, and motivation for joining CVS.
A conversation with the hiring manager focused on your resume, background, and why you want to work at CVS. In some cases this felt like a light screening interview, while in others it was more behavioral and team-fit oriented.
A live coding round, often with a data scientist or senior team members, split between SQL and Python. SQL questions could be quite difficult and involved joins, unions, window functions, CTEs, subqueries, and aggregation, while the Python portion included pandas-style tasks such as transposing, grouping, and merging dataframes.
One or more case-style interviews focused on CVS-specific healthcare and ML problems. Candidates were asked how they would identify high-risk patients from claims data, choose features, design experiments or A/B tests, and think through business problems such as reducing member costs by steering them to lower-cost care.
Final conversations with a hiring manager, director, or executive director that were more behavioral and resume-driven. Interviewers spent time on past projects, lessons learned, and why you want to work at CVS before making a final decision.
