IBM Data Scientist interview questions

Just asked to describe previous projects and answer a business case question. There was no technical question but the interviewer expected you to describe it on your own. Be aware to be very specific regarding your models or you will not get the offer.

It was very arbitrary. They give you an online coding test. And just said they are going to go with other candidate without much telling you why. First they were going to ask about one subject and then ask another instead.
