Pros
If you miss 80s (and I don't mean the music, but processes, culture, and technology), Bloomberg is the company for you. If you miss 90s, wait a bit, they are getting there, come in a decade or two. To get a good understanding of what to expect, listen carefully about the company's culture, but remember that in 80s those words must have meant something different: "Flexibility" means "Manage your time yourself as long as your manager can constantly see you". "Flat structure" means "open space" or maybe "flat vertical structure". "Hard-working" means "Keep yourself busy till late". "Agile" means "Micromanagement". "Innovation" means "NIH syndrome". "Risk-taking" means "If you screw up just this much ...". "Be bold" means "We've no idea what that means, but they mention it in every book".
Cons
If you are looking for an internship or your first job, and money is your only motivation, then go to Bloomberg.
