I applied online. The process took 2 months. I interviewed at Bloomberg (Hongkong) in Feb 2015
Interview
First Round
Brief self introduction
Then we were divided into group, and group discussions were held.
We had to rank the characters of fishy tale,
and discuss how to invest 10 million dollars.
The atmosphere was quite chill, and there were 3 interviewers, and 22 applicants.
I have accepted the second round interview offer, waiting for it.
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.
