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.
