The process took 2 weeks. I interviewed at Bloomberg
Interview
initial Phone interview; basic interview in which they ask you about yourself, why would you work at Bloomberg...
In house interview: mainly HR questions but also some technical ones. They are very friendly with you through the whole process
I applied through an employee referral. I interviewed at Bloomberg (Princeton, NJ) in Feb 2014
Interview
The interview process was very casual. 3 rounds of interviews in one day. Senior management conducted all 3 interviews. Questions were mostly behavioral and centered around your resume. They look for people who fit the culture and really want to be at Bloomberg, so you can be a genius but if you want to be an investment banker it may not be a good fit.
I applied online. The process took 5 weeks. I interviewed at Bloomberg (Hongkong) in Aug 2015
Interview
It's a group interview, 9 candidates. First, self-introduction, including your background, your interests, and taught other candidates one thing extemporaneous. Next, divided 9 people into 2 groups, and gave each group a unique resume to value the person, then 2 groups debated for that the person on the resume is the most suitable one on the job position. This process lasted about 22 min, group discussion 15min, debate 7min. Then, the third part was also the group collaboration. 9 people redivided into 2 groups, and given the question- to make an investment plan of 100m HKD, needing the portfolio to be diversify, and attaching the lasted news about why you choose this product (both financial and non-financial news). It was 20min in the third part.
