Optum Data Scientist interview questions

I performed a simple data analysis and present the results. The analysis involved transforming and merging two datasets and reporting some summary statistics. In the presentation, I answered the required questions one-by-one. Unfortunately, I did not pass this stage. The reason is unknown. If I was to improve my assessment perhaps I could have used storytelling techniques.

Wonderful interview process with very insightful discussions along with some major questions around career and CV, also the interviewers were very knowledgeable and kind, I would recommend to go through CV thoroughly
