Here is a thread that may provide insight. If in fact by finance you mean IB, I will be happy to offer some further advice?
Please let me know if I can answer any specific questions. As a career investment banker and alum of the best Seven Sister School I do have some first hand experience and opinions
FYI if I banking is the goal please note the recruitment process is somewhat idiosyncratic and unique so please consider the sources and experiences of those offering guidance carefully.
