Mindless bureaucracy, 'Culture', bad management.
They are obsessed with shrouding their incompetence with 'culture' and fallacy. I left because management were very inconsistent. I couldn't handle the idea of creating a long term career under people I couldn't trust.
At first I tried applying for jobs internally as I was convinced the problems were only in my office. I don't now believe that's the case. I liken bloomberg to an apple rotting away slowly from the inside, you won't see the issues until its far too late.
If you want career development at a smaller office, concentrate on making friends and never disagreeing with your immediate manager, even if they aren't making sense. The key is to appear busy/swamped and then make excuses after the fact as to why something turned out the way it did. The managers I've encountered have no concept of strategy, it's generally accepted that they should plan better (read: say they will plan better) and then do exactly the same thing that blew up in their faces time and time again.
All management at bloomberg should have a mandatory dictionary on their desks. They all seem a little confused what different words mean. They have analysts that aren't analysts, advocates that aren't advocates, office managers who don't take care of the office... The list goes on and on.
Also, count on a management reshuffle that has absolutely no effect on the business every 6 months or so. This will be explained to you at some point, but about 10 minutes later you'll realise they spoke for 20 mins without actually saying anything specific.
