Graduate Trading job at one of the Big Banks - i.e. Barclays, Goldman, etc

Is anyone a trader at one of these large institution's?

I would like to know because I had applied for a graduate position as a Trader at Barclays capital in London last September and have been accepted. So I have just two questions.

What is the work/life balance like of a typical trader? Is it long hours like investment bankers?

What are the fundamental responsibilities of a junior trader?

im not one but ive heard there very very long hours but congrats on the job
