Communication, leadership, problem solving, and working under pressure are the key skills in an investment banking job. You should highlight that you are flexible enough to adopt new styles and methods of functioning, while being willing to work as part of a bigger team.

Talk about your core competencies and how you used them to achieve measurable results at a previous job or during your education. Discuss your failures, how you handled the situations, and what you took away from them. Whenever possible, talk about deals you've participated in. There are few things than interest an Associate or Senior Vice President more than deals.
