I applied online. I interviewed at Bloomberg (London, England) in Jul 2017
Interview
Straight forward. The people interviewing were nice nice and welcoming. The explained the interview process, the job role in full and the skills that I would need to succeed in the role. There were a total of three rounds of interview in total and it took about 5 weeks in total to be hired.
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.
