I'm trying to get a clearer picture of some firms in Chicago. I just don't understand the landscape in Chicago, and Google proves to be useless. I found some employee home pages, but they're college kids who blog more about their escapades in Africa or World of Warcraft than anything about the prop-scape. Anyone care to rank the following firms in terms of best places to work for and best places to make money? Transmarket, Gelber, Jump, DRW, Getco, Sun, Spot, Optiver, Chicago Trading Co., ... 1) Best place to work for 2) Market share in equities, fixed income, futures, energy, etc. (estimates/guesses, don't expect people to dump the real numbers) 3) Profitability for an employee (again, guesses) 4) Easiest place to get angry and burn out (this is BY FAR the most important metric for me, as I am a happy person now and never wish to be burned out again) 5) Management Feel free to add your own firms, but please tell me of all the rumors you know either through private messages or here in this thread.
