Dell Technologies Data Science interview questions

First was a phone interview (1) with the recruiter, in which they gave details about the position and looked for preliminary fit for it. After it, there was an introductory interview (2) with the Dell member under whom I would later work directly, which contained, in addition, an elementary coding question. At the end of that interview, I received a fairly regular data science home assignment (here's a dataset, let's see what you can do with it). Then there was an interview with a data science group lead (3), in which I presented my work on said home assignment. A big plus was that much emphasis was put, aside of the technical part, on business understanding and communication skills. Later, on a single day, were the team lead introductory interview (4) and the HR interview (5). In general, the process' attitude was very professional and friendly. Interview scheduling was done through the recruiter.
