I applied in-person. The process took 1 week. I interviewed at Bloomberg (London, England) in Jun 2015
Interview
3 Stages: 1st phone call, 2nd team leaders, 3 head of Sales for the region and Head of Analytics department. All of the people were really nice, but they did expect a very high level of familiarity of our strategies globally, ancillary products and deep knowledge of competitors, so prep these aspects well
Interview questions [1]
Question 1
If you were sent to a country with no Bloombergs, how would You sell?
Sell a Boomberg to Manchester United Club?
Ancillary products- what do You know about them
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.
