I applied online. The process took 3 weeks. I interviewed at Bloomberg (New York, NY) in July 2017
Interview
Very straightforward. Behavioral Questions in the first interview. Two case study questions in the second interview and another behavioral interview with a Manager for your final interview. Nothing is out of the ordinary here. If you have prepared for other interviews using case studies, you will be fine.
Interview questions [1]
Question 1
Why this job? What about the financial markets excites you? Tell me what currency you're currently following and why?
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.
