I interviewed with Bloomberg in February 2013. I had applied online through their careers website. A couple of weeks later they setup a phone interview for me. It was a technical interview and I had expected a lot Data-Structures and algorithms related questions. However, to my surprise the interviewer didn't ask me to write any code at all. We first spoke about my resume for sometime. After that he gave me a system design question. He basically wanted me to tell him what data structures I'll use, what kind of challenges I'll face when designing such a system and how I'll overcome those challenges. The interviewer was very nice and it was more of a discussion than an interview which was nice. 3 weeks later I got an email saying that they are coming to my campus and wanted to know if I'll be available for an interview. This time there were two interviewers. They started by asking me questions about my past projects and internships. The interviewers were a bit unprofessional in the sense that while I was answering one person's question the other person would suddenly change the question and ask something else. They asked quite a few data-structures and algorithms related questions.
