I applied through college or university. The process took 1 week. I interviewed at Bloomberg (Champaign, IL)
Interview
Bloomberg was on campus and I submitted my resume. Got invited to a first round group interview. Five people in a group and discussed about a piece of commercial news. We were given 15 minutes to draw some conclusions to the questions and give a presentation to the interviewer.
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.
