Bloomberg provides a solid benefits package for its employees. It is one of the few companies that I have worked for that pays the entire cost of health insurance for its employees. The company also provides 3 meals a day at "no cost" at its Princeton, NJ location. If you are interested in state-of-the-art analytics for the financial markets, this is a great place to work.
Minpunten
The company is very "metrics driven". Many of the jobs are very stressful and tedious. Management has little trust in its employees. And for a modern company, they are not accomodative to employees who seek work-life balance. Career opportunities are primarily in the company's New York HQ. Employee morale is very low since Mike Bloomberg has left to be mayor of New York. The company is very youth oriented. I have seen few employees over 40 promoted or treated well. There is a hidden, and at times overt, atmosphere of hostility toward older employees. All employees are expected to fit the "Bloomberg mold." There is little tolerance for individual differences.... Finally, management is quick to point out shortcomings, but rarely praises things that are done well.
