I applied online. The process took 1 day. I interviewed at Bloomberg (London, England) in Sep 2016
Interview
Phone interview (1st stage): the interview lasted for around an hour, a lot of specific questions were asked about Bloomberg, its products its competitors and the actual market. Interviewers should be aware about the company in details and research a lot about it, about the culture and the motivation that made them apply.
Interview questions [1]
Question 1
Why Bloomberg? Why Sales? tell me about you.. Why working in the financial sector?
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.
First was Hireview, 1 Hour interview with two team leaders, and assessment centre, consisting of tests, networking, and a final round interview with two team leaders from analytics and sales departments respectively.
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.
