I applied online. The process took 4 weeks. I interviewed at Bloomberg in Dec 2010
Interview
Got contacted by a member of their HR staff. Basic ques such as why us?who are our competitors? what do u know about the program?walk me through your CV?what recent market news have you followed?
I did ok, im guessing since they invited me to go to London the next day, but the event was not for another 6 weeks
have not gone through that interview yet but based on what others have experienced sounds tough
