I applied online. I interviewed at Bloomberg (Central) in Feb 2015
Interview
Group Interview, with a group of 5 people in the main office in Hong Kong. Was interviewed by a recruiter in a chillax atmosphere. The recruiter was funky and friendly, trying to loosen up the morning tiring mood, and asking us to tell him more about ourselves, including an interesting fact. Then we were to finish off two tasks, one is to advise the recruiter on how to invest 10m dollars, and the second is to rank our preference towards the characters in the little mermaid tale, and to come into a consensus. Lastly, to take a stance in supporting the ranking and to make a short persuasive speech.
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.
