I applied online. The process took 1 day. I interviewed at Bloomberg (New York, NY) in Dec 2016
Interview
There was couple of phone screens that they asked programming questions as well as some basic questions on machine learning. The interviewers were usually interested to know how much you are familiar with new trends in machine learning such as deep learning topics. After passing the phone screens successfully they invited me for onsite interview. I should say I find Bloomberg office very fancy and modern. I had first a presentation of my Ph.D. research followed up with 3-5 in person interview that they examined depth of my knowledge about programming, machine learning and general system design skills.
