Pros
Yes you learn a lot, and get to go one some decent meetings. Yes you can have a comfortable career in sales. And yes, one of the perks is the pantry 3-4 years at Bloomberg now, very competitive salary, not far off doubled what I started on. International movement.
Cons
Should you apply for a job because of the free food. Absolutely not. I am massively surprised that that is the first thing that comes to mind when employees are reviewing their life at Bloomberg. Work should be about what you are doing not what you are eating. Working in the "Analytics" department is very misleading. In no way are you an analyst. In no way are you learning the skill set to become an analyst. You are not reviewing balance sheets, or capital structures, or debt distributions. You are a minion, a cog in a wheel, a beast of burden, forever in fear of the dreaded QC. You churn out MSN/AOL style chats wherein a client comes in and asks a question. You don't know the answer, you pass on to someone more experienced. If you want to go to sales and have a 9-6 job (8-6 in London) then great. Nice salary (so you can't leave) and essentially a new job every 2 ish years. New team, new challenge can't complain. If you want to get involved in the world of finance, don't touch bloomberg with a barge pole. It is a market vendor, nothing more. Internal movement into the the more analytical aspects of bloomberg is near impossible.
