I applied online. The process took 5 days. I interviewed at Bloomberg in May 2010
Interview
It started with a group interview then several 1 on 1s. 1-1s were mostly behavioral questions and a bit of the technical questions to test your interest in finance, such as what is an interest rate swap. They are looking for someone with strong communications skills, client focused and highly flexible in achieving goals.
Interview questions [1]
Question 1
How would you handle an extremely difficult and demanding client?
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.
