Ha ha ! Walking with a long coat and looking impatiently at train timings ?
You know as an international, I don't have any incentive to live outside London. So I actually live in zone1, no impatient waiting for me. I live close enough to even walk to work now; I used to hate taking the underground, its too crowded and stuffy, and these days I don't have to.
As for the attire, here is the other thing. I am not a "suit" (refer : entourage). So I hate wearing suits to work, and I don't. I would typically be seen either in my informal black wind cheater or a leather jacket. So if you were to run into me, you would not imagine I am a "banker". Thats the thing, S&T is chilled out. We are trading on screens and working on the floor, so we don't have to show up wearing a tie and a suit to work. Formal shirt and formal trousers ... and jeans on Fridays :D
The whole excitement bit as I said is really person to person. What works for me may not work for you. But I disagree that this is not worth trying. The only way to get into the industry is by applygin straight after school. Only two kinds of people get hired, either fresh starters or lateral hires from other banks. There is nearly 0 cross-industry hiring. So its worthwhile taking the shot. Also, given you just get out with a load of debt post B-school, it is a good way to try and get ris of some quickly !
