The Cigna Group Data Scientist Interview Questions
& Process

The interview process was smooth, and they were quick and responsive to me throughout the process. It started with a recruiter screen, which was simply about me explaining me my work experience and the next round was a technical round, where two team members asked me ML and SQL questions.

I applied online and received a rejection email within two weeks. Then the hiring manager reached out to gauge my interest in her team. After I agreed, I had a very unpleasant call with the recruiter who was condescending and made me doubt myself. I almost withdrew, but the hiring manager was nice, so we had a short talk the next day. After that, I was invited to interview with the director for another 30 minutes. He didn't answer my questions about the company's long-term ML vision. Both interviews were conversational, focusing on my past projects rather than technical questions. I informed them I had competing offers and was busy, so I needed a prompt decision after the director call. The next day, I received an automated rejection email. I tried to get feedback from the hiring manager but received no response. It was a very negative experience.

I was interviewing for a Senior Data Scientist position. The interviewer started by questioning the existence of analytics and ML teams in my company, which I had to spend 10 minutes explaining. Then, he asked me several questions on forecasting, statistics, and ML concepts, all of which I answered correctly. Although the interview was scheduled for 30 minutes, this discussion went over by 10 minutes. He then asked me to open an editor to check my Python coding skills. There was a technical issue with the screen share on Cisco, and after asking me to reconnect, he left the call for 5-7 minutes. Upon rejoining, he seemed unaware that coding could be explained either through an editor in the meeting window or by writing with pen and paper. He then asked if I had any sample datasets handy to ask questions on, which I found to be an unreasonable request. He then stated another meeting would be set up to check my coding skills, but this never happened. I later learned from HR that he had rejected me. My observation was that the interviewer was unstructured, unorganized, and unprepared. I feel that if an interviewer is going to exceed the scheduled time, they should not make a decision based on the extra time taken. I would suggest either being well-prepared or canceling the interview and finding someone more knowledgeable. Playing with a candidate's career due to ignorance and foolishness can significantly impact someone's future, especially if they don't have other offers.
