Applied to Bloomberg through career fair. A good thing is they take non-computer science majors as well for software development positions. I had one technical interview and heard back from them after about 4 days for the second technical interview. After this, I was given a date immediately for the next round of interviews, which were financial and HR. Financial is bare minimum and they also want to see your problem solving approach in general. HR was quite usual without anything significant. The people seemed to know well. My second technical interviewer was quite knowledgable and knew the stuff he was talking about. There was another interviewer with him who didn't speak much. The first round was with the person whom I met during career fair.
