I applied online through the website in October received an email on the same day inviting me to complete a video interview (recorded). I had 3 days to complete it. You receive a link to the video interview, there are 9 questions in total. Some really basic, other that I found more complicated. Overall you really need to prepare yourself, know a lot about bloomberg, its clients, the job you're applying for, Bloomberg's competitors... You only have 90 seconds to answer so you need to be concise and complete at the same time. Before recording you, you have 1 min before it starts recording automatically.
