Bloomberg Analytics&Sales interview questions

It was a first round group interview. There was 20 candidates, 1 interviewer from the Human Resources Department, and 2 interviewers from the Sales and Analytics department. We went into a big room, candidates are separated into 4 groups. The staff from Sales and Analytics first gave a introduction about the company. Then we had group discussion.

My telephone interview was delayed for a week. When I was finally interviewed, it lasted for 13 minutes and the questions I was asked were mainly motivation (Why Bloomberg? Why this division? What is the competitive advantage of our company) and conventional competency-based questions.
