I applied online. The process took 4 weeks. I interviewed at Bloomberg (New York, NY) in Mar 2014
Interview
Applied through company website. Initial contact and informational interview from HR. 2nd and 3rd interviews over the phone, one with Sales and one with Analytics desk. Final at the NY office. Overall, the interviews weren't too taxing. Know a lot about the company, what they do, culture, why you fit in, etc. Have a general understanding of the markets, financial statements and what role Bloomberg plays.
