I wish I hadn't bothered!
I was contacted by an enthusiastic recruiter. I was pointed towards an online portal where I had to essentially dump my CV into their online forms. The process moved very quickly onto a telephone interview. I was told this would be technical C++ questions, but it turned out to be a high-level discussion about fit for the team (which was very, very encouraging).
HR were then entirely incompetent. After a couple of weeks of silence, they asked at 7 pm if I could interview the next day. We settled on a more convenient date, and I went in for a day I was told would complete the interviews (technical and HR). In fact, I had two technical interviews, and no one bothered to tell me the hiring manager and HR weren't available that day until the end of the planned interviews.
I received an automated email after two days saying they would not be extending an offer. I requested some more detailed feedback. After three weeks of requests, the message was I was not "technically strong enough," which tells me nothing from a purely technical interview. Compared to Google's face-to-face interview process a couple of weeks prior (and the excellent feedback I got from that), Bloomberg was utterly useless.
