I applied through a recruiter. The process took 2 weeks. I interviewed at CVS Health in Mar 2021
Interview
Terrible process. Where to begin? Complete disorganization from the Aetna/CVS schedulers. Every email from their side included 3 of their hiring staff and yet still things were bungled. For instance, not notifying me that the person I had been scheduled to meet with had told them he couldn't make it, causing me to remain on an empty Zoom link waiting. Can you believe this happened more than once. Plus, the interviewers also seemed confused over who I'd met with and hadn't, presumably because of the terrible internal communications.
I had around 6 interviews total. One interviewer, who is in a more junior role, interviewed me twice for some reason. He had a habit of asking very vague questions and of using every opportunity to boast or talk about himself. When asked for clarity (i.e. "are you asking X or are you asking Y") the interviews predictably disintegrated. A classic indicator of bad management is not being careful enough about who is conducting interviews.
Most of the other interviewers were friendly and seemed to be working on interesting projects. Even though the role was advertised as technical, several of the interviews were more like consulting "case question" style, which I wasn't really expecting (and am still a bit confused why they asked).
Interview questions [1]
Question 1
They would describe an analytics case (such as wanting to determine causal variables for someone responding to incentives) and want to hear brainstorming.
Two first-round technical data science interviews for two different roles within CVS Health. Both interviewers were very nice to speak with, however, their approach—and consequently, my impression/experience—was completely different.
SQL Interview (should have been easy, right?) – Terrible experience! Three or four well-defined tasks were given. However, the partially written SQL queries and the lack of direction on whether I was required to modify the existing code or implement my own solution left me scrambling to debug the poorly written queries before even proceeding, as the original queries failed to run from the start. Oh, and the interviewer simply dropped the code into CoderPad, went on mute, and seemingly did other things, making it impossible to ask questions.
Python Interview – Excellent experience with the interviewer. The question was moderately challenging (LeetCode medium or a simplified hard), and although I wasn’t able to fully complete the solution in time, I was given a helpful hint along the way.

I applied online. The process took 4 weeks. I interviewed at CVS Health (Woonsocket, RI) in Mar 2023
Interview
Standard process, start with an HR call to figure out background match and then a technical interview with live coding and some basic stats/ML concepts and then a case study. Then a case study interview with the hiring team, and finally a panel.

I applied through an employee referral. The process took 2 months. I interviewed at CVS Health in Sep 2022
Interview
technical, work experience, data science use case, and HR interviews - one each. I was asked to solve a technical problem statement as well. Having a decent understanding and background in Statistics is a plus
