Pros
Interesting work to research. Getting paid to read the news. Working with really smart, well-travelled people, based all over the world. Flexible working opportunities and fine hours. Some travel and research opportunities.
Cons
Overall, appears to rely on working young, smart people hard for a few years to create analysis that more senior members promote and sell. Not a lot of clear training opportunities for younger members. Not great money and really opaque pay and promotion structures. Really high HR turnover and a bit of a member's club mentality means that grievances are difficult to lodge. Managers heavily direct the ethos of their teams. There is little apparent centralised control over them, meaning that their personalities heavily affect their teams working environments, and also how much feedback and training their teams receive.
