I interview for the position in the London office. The interview process - at least in my specific case - was extremely long (around 5 months) and stressful because of that. It's structured as follows: - Numerical Reasoning Test; - Phone interview (October), which is merely motivational (very few technical questions) and lasts for about 45minutes; - Face-to-face with Analytics and Sales TLs (November). In this specific interview you get grilled with technical questions - so be prepared. Both situational cases and technical questions (define hedging, what is a call option, what is a straddle, sell me an option). In my opinion this was the hardest interview because interviewers are trained to make you feel under pressured and to a certain extent uncomfortable. It lasted for about 1h and 30m; - Face-to-face with Managers (February). I loved this interview. I felt like they really wanted to get to know me as a person rather than as a candidate to test my fit in the Bloomberg culture. Overall, tough and long process. But, in the end, I was offered the position so I guess it was worth the pain. (?)

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.
