Emailed someone in HR who got me in touch with a recruiter, they sent me a position to apply for and after about 2 weeks I got an email asking for a phone interview. My phone interview was very short, maybe 20 minutes really simple questions-- why bloomberg? where do you want to be in 5 years? They called me back about an hour later asking for a video interview because I am not from the UK. I scheduled that and then that one lasted about an hour. Slightly more detailed, asked specific questions about my CV and projects I had previously worked on. I didn't think I did so well on it because I didn't know the answers to all the questions but I think they really enjoy people who are eager to learn and interested in finance. They called me back a few hours after the interview and scheduled an in-person interview in London, which I haven't gone to yet, so do not know the outcome.
