I applied through an employee referral. The process took 3 weeks. I interviewed at CVS Health in Mar 2023
Interview
The interview process consisted of three rounds. The first round was a video interview, followed by a technical interview in the second round. The third and final round included back-to-back interviews, one focused on business and problem-solving, and the other technical in nature. The recruiter provided me with information about each stage of the interview process, allowing me to prepare accordingly. The interviewers were all friendly and professional, and they were willing to help and clarify any questions I had throughout the process. Overall, the experience was very positive, and I gained valuable insight into the company and the role I was interviewing for.
Interview questions [1]
Question 1
How to handle categorical data and missing values?
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.
