route to IB- economics or accounting and finance?Watch
Also, would a degree of accounting and finance from LSE, give you an edge over an undergrad graduating with an economics degree from cambridge?
To answer your second question - no. If anything, all other things being equal, the Cambridge grad will have an advantage over the LSE grad as Cambridge has the more prestigious brand name. This advantage may not be so large for investment banking, but will be a lot bigger for top-tier management consultancies, elite asset management firms and private equity, which are extremely selective and hire only a handful of grads.
