IBM Data Science interview questions

In the assessment there is one sql question (which included with two questions )and one machine learning question. I think sql was super easy and the machine learning question was tough.

The interview process was in the regular way: - first interview general questions - SQL and English interview - IQ on-line tests - a lot off... - technical interview Friendly environment, interest to knows you, not only to test you. I leaved the interview more confident than I entered
