The process took 1 day. I interviewed at Bloomberg (London, England) in May 2010
Interview
The interview process was generally quite straight-forward compared to a lot of the banks. After an online application you're required to complete a test, which you can complete in one of several programming languages. It's very technical and mainly consists of 'look at this code, figure out what's wrong with it' problems, all emphasising syntax over anything else.
Upon completion of the test you might be offered an interview. It'll consist of technical interviews with people of varying levels of seniority, starting with the most junior. The questions are all programming related and there are no HR type questions at all. If they like you they'll offer you a job, it's that simple.

Interview
I applied for financial software developer several weeks ago, got the email from them including a link to take a online test last week, it's like an IQ test,questions are like: graph rotation, basic math problem,flowchart problem, GMAT logic problem. After one day got the email from them to set up a phone interview with me.
The process took 4 weeks. I interviewed at Bloomberg (New York, NY) in Nov 2009
Interview
applied via website, got a call to setup aptitude test and then a technical phone interview. Was asked 4 math puzzled and one sort program which I got correct. Was also asked why software development and other similar kind of questions where I totally screwed up since I am not from a computer science background and could not explain why I wanted to get into coding.
