I applied online. The process took 4 months. I interviewed at Bloomberg (Londres, Inglaterra) in Feb 2017
Interview
Very long, badly organised. The team leaders do not know anything about you and they just show up there with questions to make you fail the interview. Not pleasant. Bad treatment. Such a shame that big companies hire these kind of people to carry out the interviews. They called me three times to male sure that the languages I spoke were in accordance with their database.
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.
