Investment Banker

Requirements for Investment Bankers
A Bachelor's degree in business administration or a related field like finance is required to become an investment banker, though many employers prefer or require a master's degree. Because these professionals use mathematical models to predict potential outcomes, most undergraduate programs require students to complete courses in calculus and statistics. Advanced courses in these majors generally cover concepts ranging from mergers and acquisitions (M&A) to financial accounting.
Due to keen competition for jobs, students are generally advised to complete an internship prior to graduating. Internships allow students to work within an investment bank, analyzing assets and portfolios using valuation models. These positions help students hone their analytical skills, as well as network within the field. Connections made during internships can help aspiring investment bankers secure a job after graduating.
