Pros
Pay and Benefits are very good. Job stability at Bloomberg is very good. The company encourages employees to volunteer with various charities.
Cons
The company insists that everybody comes to the office every day. Until recently working from home was never allowed. Even now it is highly discouraged by management. Software is hurried without good design and with little documentation. There is a lot of proprietary software and after a few years your expertise starts to decay. The open plan seating arrangement does make communication between employees better but the noise and interruptions make concentration impossible. The corporate culture with its automated system of tickets give you the feeling of being constantly rushed to deliver. The overly complex and poorly organized software lowers productivity.
