Pros
Bloomberg has a very systematic approach to sales. If you are able to conform to the Bloomberg way, you can succeed. There are multiple opportunities to learn about other areas of the business and with the media/news arm, it gives finance people exposure to a different industry. The benefits at BBG are fantastic.
Cons
The grading system is very rigid here. If you are an out of the box thinking or an independent type of employee who does not like guidance, this may not be the place for you. The company rewards loyalty over intelligence and hard work. Managers have too much power here. There is not a lot of work/balance life as the company likes to advertise. Some "lifers' feel comfortable taking "work from home" days but generally its frowned upon and you are expected to be in the office as if you are working on the clock.
