      Anonymous Interview Candidate

      No offer
      Negative experience
      Average interview

      Application

      I applied online. The process took 2 weeks. I interviewed at CVS Health (New York, NY) in Jun 2021

      Interview

      Applied online and promptly received email from HR for a conversation. The recruiter was nice and described about CVS and role elaborately. Salary was also discussed before next round. The following round was technical phone interview where I was asked to solve questions related to SQL, Python, Data Science. The interviewer was very couteous. I solved most of the questions and if there was gap, he hinted me. We had a great convesation. Before the end of the call, he clearly mentioned that I will get a call from the recruiter soon for the next rounds. The recruiter will discuss how they will arrange the next round, onsite or offiste. I was very happy about the interview and emailed the recruiter about my experience. She promptly acknowledged. With my much surprise the very next day I got a rekection email from the recruiter mentioning they are going ahead with other candidate. I am not sure how things changed within a day. Its only the team knows. But a good convesation or good interview doesnt mean that one will be for the next round. Unsaid things happen after the interview.

      Average interview

      Application

      I applied online. I interviewed at CVS Health in May 2025

      Interview

      Recruiter screen first. Recruiter told me the next round she’d schedule would be behavioral. She totally. misled me. It turned out to be a purely technical python and sql interview with ML questions (was interviewing for an AI role). I wish I had just known because walking into that interview by surprise is not fun.

      Interview questions [1]

      Question 1

      How would you address overfitting in an ML model?

      Easy interview

      Application

      I applied online. The process took 2 weeks. I interviewed at CVS Health (New York, NY) in Feb 2025

      Interview

      Interview process was generally unprofessional. For my first round, my interviewer never showed up to the interview, no email or anything to notify me of any cancellation. Several hours later, I received a very short email (no apology) that the meeting software was having issues and that I need to re-schedule. I rescheduled, and in that meeting the interviewer did not show up until roughly 15 minutes into our 30 minute call. I went on to the technical screener, which was mostly about a dataset dealing with insurance claims for radiology. I am not extremely knowledgeable about insurance claims and different industry metrics associated with insurance claimants, and so I probably did not answer several of the questions very well. I spoke to my roommate after who deals with health insurance data and said it would be difficult to answer questions correctly without a prior understanding of what some of the metrics are measuring, and how they are calculated. Questions were a mix of SQL and Python. I felt that the Python questions were a bit pedantic - instead of trying to solve for a genuine solution, most of the questions were essentially "Do you know this specific pandas command?(shape, info, describe, etc.)" At the end, asked about A/B testing and experiment design.

      Question 1

      How would you design an A/B test experiment to determine the success of flu shot brochures on vaccination rates?
