I applied through an employee referral. The process took 2 months. I interviewed at CVS Health in Sept 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
Interview questions [1]
Question 1
General Data Science interview preparation would be good enough
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.
