I applied online. The process took 4 weeks. I interviewed at Bloomberg (London, England) in Nov 2019
Interview
Interviewer is friendly but the questions are difficult.....The OT was easy to pass, video interview was a bit difficult, better find someone do it you as some competency questions are quite hard to think of an example. Followed by the Telephone interview, unexptected questions will appear......
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.
