Sales sounds awesome (building and maintaining relationships) but as a career, it makes you easily replaceable.
Trading is pretty much the dream but it's like modelling - you last maybe 7-8 years then once you hit a certain age(assuming you don't get fired in between), you burn out and you leave, with no exits other than ... more trading.
Structuring seems like the perfect in-between, and career-wise there are only a few structurers in a group (ex. 15 salesmen, 8 traders, 1-2 structurers) making them very invaluable. Fire the structurer and he'll just get snatched by another bank, period.
For the most OTC desks (FX, rates, credits) don,t you guys agree that in S&T, the structuring role seems like the general "best" spot career-wise?
