"Mike Bloomberg stresses the importance of keeping the entrepreneurial feel of the company, which means that even though the firm is 25 years old and has several thousand employees, it often feels like a startup." Indeed, the Lexington Avenue headquarters has no separate offices (though the "dazzling" building is quite "amazing"). Also like a newly established firm, the "company expects long hours and expects you to give your all," comments another source. Insiders say "teamwork is very alive here," and they gush over "the caliber of people" they work with. "We have, literally, rocket scientists working on the computer hardware and software." It is this enthusiasm and level of expertise that "keeps Bloomberg active and creating new ideas." "The whole company is wired to the net and connected to every other Bloomberg office in the world -- communicating with your colleagues around the world is a push of a button away." On the other hand, some techies are not so in awe of the Bloomberg systems. A programmer offers: "The proprietary system is not that transferable to the outside world" and adds Bloomberg "is not a place where R&D staffers can hope to maximize their long-term marketability."
