Accounting
If you don 't have a deep background in accounting, but if you are strong in math, then don 't worry, you 'll be able to pick it up fast enough once you 're on the job. If you do have a background in accounting, then it gives you a nice edge.
Corporate Finance
Corporate finance is different than accounting in that corporate finance relates to valuation and financing decisions. The purpose of accounting is to create statements that lay out the historical financial health of a company for management and investors. The purpose of corporate finance is to apply the results of these statements (along with intangibles such as the strength of the industry and the management team) to a valuation model in order to arrive at a value for the company.
