Machine Learning Engineer Interview Experience - United States
Process
Had a call with the interviewer in Round 2 via a contracting firm. Round 1 was with the contracting firm, and Round 2 was with the CVS interviewer. Both were technical rounds focused on typical machine learning frameworks and MLOps-related questions.
This was one of the most unprofessional interviews ever. The CVS interviewer started speaking about the quality of candidates from the contracting firm and budget issues, etc., in front of me. It was a bit disrespectful, as it was his impression about me before even beginning the interview. In 15 years of my professional life, I've never met such an interviewer. We had to end early as I lost interest and started saying no to anything he asked.

CVS Health Work Experiences
- 5.0Machine Learning EngineerMachine Learning Engineer • Current EmployeeNashville, Tennessee, United StatesNovember 23, 2021Pros: • 3+ years of experience in data analytics, statistical modeling, visualization, and machine learning.Cons: Proficient in the Software Development Life Cycle, including requirements gathering, design specification, and testing as per the cycle in both Waterfall and Agile methodologies.
- 3.0A decent place to work, but not very tech-focusedSenior Software Engineer • Former EmployeeNovember 11, 2025Pros: I worked with some great people.Cons: They're moving in the wrong direction with tech decisions, pushing forward quickly with little regard for quality or long-term thinking. Lots of mobile engineers work too much -- nights and weekends, even. This makes little sense since you can't quickly push a production fix to the App Store or Play Store; there's a whole review process that slows things down. So working production support over a weekend as a mobile engineer makes zero sense.
- 4.0A Mixed Bag at Aetna/CVS HealthStaff Level Engineer • Current EmployeeNew York, New York, United StatesNovember 9, 2025Pros: Access to free upskilling resources and opportunities to develop deep healthcare expertise while working with cutting-edge technologies. The company actively adopts new tech trends, and strong remote work policies offer genuine flexibility.Cons: New employees joining at the junior level face a lengthy path to equity compensation, with no RSUs available until reaching the Lead level—typically a 4-5 year timeline. Additionally, compensation challenges include non-competitive base pay, limited bonus structures, and modest annual raises.
