Mu Sigma Data Scientist interview questions

HR contacted me to mention an opening. Rather than explaining about the profile or anything that would interest me, he mechanically kept mentioning the requirements as if reading from a paper and scheduled a date. There were 3-4 people during phone interview - and most seemed to be quite young. Again, there was no interaction, no introductions, and they made it sound like a high school viva. Asked a case study question - and just when I was at the peak of explaining my solution, they interrupted and immediately asked a totally off-the topic question. This experience turned me off.
