Had a short phone interview (about 20 min) and the day after I was schedule to have a 2:1 interview. The questions were pretty much the same: Why Bloomberg, How do you deal with an angry customer, what Bloomberg customers expect from our service, example of a stressful situation and how do you deal with it.
I applied online. The process took 4 weeks. I interviewed at Bloomberg (Londres, Inglaterra) in Dec 2012
Interview
I applied for a non-computer science entry level position. They got back to me really fast (a couple of days). The phone interview was fast, they asked about my university work and any programming experience. They asked afterwards about stack/ heap, garbage collection in c++ vs java, and other simple things. I was invited to a face to face interview, where I was asked why I wanted to work for Bloomberg, and what makes me a sensible choice.
They asked about finding the 1st missing element in a sorted N-1 set of numbers (they were looking at sublinear complexity algorithms, not the sum from 1 to N minus the sum of all elements in the set, which is linear complexity).
They asked about finding the maximum loss of a trading day given the numbers, and how I would implement it.
They replied roughly 24 hours after the face to face interview. It was a fairly nice experience actually (yes they do have free snacks and coffee at the office and very beautiful aquariums).
