It is a very open environment and culture at Bloomberg. The People there were nice and its mainly behavior questions that they would ask you. First you have to explain your resume. Then its questions from what product do we sell, weaknesses and strengths, and any other question that can explain who you are such as if you could be anything in the world what would you be. They want the right candidate for the job. I had two interviews back to back for an hour and toured the place a bit. I went to the second round but did not get to the third (last round).
