Let me reply in a different way, you posted about this very topic almost 3 months ago now. I will discount the thinking that no job offer will be open for that long. But what is troubling is the fact that you have trouble making up your mind. I apologize if this sounds harsh, but this indecisiveness is absolutely deadly to a trader, even to a lesser degree, an ibanker (let's say when you are competing for deals).
You probably heard the saying that trading requires "balls", to interpret that means you will have to make gutsy decisions *every* time you enter the market, especially if you are trading some size. It is a gamble, there are absolutely no sure things. The last thing a trader should do, is staring at the screen, and thinking for 10-15 seconds and let the trading opportunity slip by, the time to act is *now*, assuming you have some evidence (model, etc), but it is still a big gamble after all For instance, I run an *automated* trading system, which means I can be indecisive (and I am an academic, so I can agonize over every little decision choices), right? No, I make educated (and some non-educated) guesses everyday, do I make stupid mistakes that cost me money (and sometimes a lot of money), absolutely, but that's the cost of making a real decision.
Life is about choices, yes, in an important one like taking a first job, it pays to look at all the career pathes, get some advice, try to make an informed decision, etc. But make a decision, be clear to either firm, "hey, I am coming, and I am ready to plunge head first into a career with your firm, what can I do to prep myself further?" Be aggressive, make a commitment.
