I applied online. The process took 1 week. I interviewed at Bloomberg (London, England) in May 2014
Interview
The office is very nice, all glass and open spaces, free food and coffee in the waiting area. The interviewer was professional, most of the questions were standard (e.g. why Bloomberg, where do you see yourself in 5 years, what was the last book you read etc.). This was supposed to be a second-round, after a telephone interview, however I was fast-tracked to the one-on-one interview.
Interview questions [1]
Question 1
You have 30 min to write a short piece of research on a stock of your choice.
