I applied in-person. The process took 1 day. I interviewed at Bloomberg (London, England) in Apr 2016
Interview
30 minutes with a manager of the department. Lots of interactions.
Communications skills and language skills are highly observed by the interviewer apart from the interest in working at Bloomberg so you should be prepared at all times when asked to sell yourself and sell something.
Financial-related questions (Regulations, Dodd-Frank Act, IFRS 9 etc)
Interview questions [1]
Question 1
Why Bloomberg? Why Finance?
How do banks make money?
Sell me something you like.
What's the CEO of Deutsche bank preoccupied about? (as of April 2017)
Begins with a personality assesment that also includes puzzles meant to test pattern recognition. The assesment and the personality quiz takes about 30-40 minutes and requires no preperation before hand.
Multi step interview process, they have you submit a recorded video interview, then you get selected for a virtual super day where they interview a bunch of candidates at once, then you get an in person. Know about finance and know as much as you can about Bloomberg and its business. Have a good take on AI in finance.
