Pros
Great people and management structure at the top. The Bloomberg for Enterprise team was an extremely exciting area to be part of, and I am sure that will continue to be a rewarding place to work. Challenging and diverse work. There is a lot more flexibility and willingness to implement change in a dynamic manner than at other big organisations. Profit apparently goes directly to charity, and employees are encouraged to volunteer for a variety of charitable initiatives. It is very rewarding. Amazing summer parties.
Cons
There is little regard for work-life balance. The hours are 8am - 6pm in the London office, which is longer than either of the other two regions (APAC and Americas), and you will be expected to far exceed this. Whilst a lot of managers are happy to allow a degree of flexibility, there are a lot of managers who are very anal about time keeping. Badges mark when everyone is in and out of the office and makes it feel much more like a "big brother" society than the open culture they claim they are trying to cultivate. Prepare to live to work rather than work to live. The biggest flaw at the company is cronyism. There are a number of people who have got into middle management positions, with no relevant experience or credentials, other than being the hiring manager's friend. You can easily tell who they are, they don't actually do any work and delegate everything to their more capable team members, whilst ensuring that they take all the credit of course. They end up being far more a hindrance than an asset to the company. Whilst networking is an important and natural part of any job, the extent to which it counts at Bloomberg needs to be looked at. It isn't a widely spread problem, but it is a problem. The upside is that senior managers who are not directly in the same reporting path easily spot this happening and are adept at cutting said managers out of the loop so the work can actually get done.
