IBM Data Science interview questions

In-person Interview came following three months of phone discussions and interviews with HR. Discussions with HR entailed answering generic questions on location preference, availability dates, salary expectations, etc... In person interview consisted of three 1-on-1 discussions with IBM employees. Each IBM employee was from a different discipline (ie. Sales vs Consulting vs Project Management). The questions were not "textbook" rated if you will, rather, the interviews were more of a "back-n-forth" discussion on how I would handle a given business scenario that could/would come about as an employee at IBM.

Virtual screen, then round with Data Scientist, then group final round. Overall, relatively straightforward. Useful to study basics of statistics, and some example machine learning methods. Describe prior projects/datasets that you worked with.
