Investment banks look for five main things in a resume - quantitative & analytical ability, initiative and motivation, communication, teamwork & leadership skills, and passion for finance. To be successful as an investment banker requires a very specific set of hard and soft skills.
Arguably one of the most important aspects of investment banking is understanding numbers. Investment bankers want to know that you can solve quantitative problems, especially early in your career, and you have little to no experience.
Investment bankers also want to know whether a candidate has the initiative, motivation, and energy to deliver strong results. For example, have you brought in new customers or increased revenue into your company? Maybe you've proven yourself to be a self-starter who goes above and beyond requirements.
Writing and speaking efficiently and effectively is another key attribute that suggests to an investment banker that a candidate will be successful working with clients and colleagues. Also interpersonal skills and teamwork. Banker investment is, after all, a team effort.
In this role, you generally interact with teams of executives from client companies. Also, investment bankers are looking for leaders. Individuals who find a way to get things done and people who can handle the job's pressure-filled environment.
Finally, investment bankers want to know that you know exactly what you're getting yourself into and that you have a legitimate interest in a finance career. This is especially critical for those who transition into the workforce from school.
