Q:

What have you learned from your studies that can be applied to a career in investment banking?

Answer

You might initially think that if you haven’t done a degree in finance or economics you haven’t got very much to offer an investment bank, but you’d be wrong. Any numerate discipline will have given you a mathematical toolkit that will come in useful in technical banking work, and any good degree proves that you’re intelligent, hardworking, and effective under pressure. Extra-curricular activities may have given you a wealth of other skills that are valuable at an investment bank, such as being able to juggle a number of commitments and work with others.
