Pros: Friendly and approachable peers and managers. Care about training their developers in new technologies.

Cons: Unconventional technology stack with lots of in-house software (although this is changing). Fairly large organization, so things can move a little slow.

Pros: - Free "sneaks" (but the selection has become worse) - Nice office building in a good location - More stable than investment banks and other financial service firms

Cons: - No privacy in the office. - Small desk, no cubicle. - Cost cutting: benefits have been reduced year over year and are getting worse. - Slow growth. - No more free medical insurance. It used to be free, but now the company charges insurance premiums. - High turnover. Many people leave within 2 years or less. - Very political place, very hard to get things done. Senior management does not want to take risks by investing in new projects. - Flat structure, hard to grow. - Long working hours. - Below market average compensation.

Pros: Line on the resume. Good pay, but if you count all the hours you really work, it's less impressive. The building is really cool: multicolored glass, transparency, lots of open space. Events scheduled for interns. Flexible work hours.

Cons: Work is not really challenging. Lots of repetitive work. Need to fill out programmer's notes every day. If you're a programmer and you hope to learn more about finance by working here, it won't happen. If you're an intern, you cannot bill more than 40 hours per week. Almost everybody works more, but you won't be paid for overtime. Free food and drinks are always there, but if you're health-conscious, most of it won't be of much benefit to you. IB - "Instant Bloomberg" - instant messaging for Bloomberg employees - can get in the way of work. Old technology.
