I Interviewed with representatives of the company at my school's career fair. I was asked to come back the next day for an interview. The interview lasted about 2 hours. I was not asked any programming language question because of my non CS background. The asked me only one behavioral questions. The rest were aptitude and problem solving question. For the first half of the interview I was asked problem solving questions from more two experienced Bloomberg employees. They took me into another room where I further interviewed with two entry level employees.
