IBM Data Science interview questions

You will be invited to do a test called cognify which has several games in it, the time given is quite limited so you shouldn't think too much about each question.

Games based screening, then code tests in SQL, python. The SQL was a rank top 5 based on sub-query and the python was a market basket analysis. You could not import packages to make the MB simpler. Same was true for R (they let you choose the language).
