I'm a rising junior economics major and computer science minor at a good target school aiming to get intosummer. I just finished at a MM investment bank primarily focused on M&A. I've taken one financial accounting class and will also take an intro to financial theory class this autumn for the econ major. I've heard that all else equal, a Wharton finance major will be grilled harder on technicals than, say, an english/liberal arts major. At what level of technical knowledge would I be expected to know?
