An investment banker is a professional who provides financial services to corporations, governments, and other entities. The main responsibilities of investment bankers include advising clients on financial strategy, raising capital, assisting with mergers and acquisitions (M&A) transactions, trading securities, creating structured finance products, and underwriting securities offerings. Investment bankers must have a strong understanding of financial markets and products, excellent analytical, communication, and interpersonal skills, and the ability to work under pressure and handle multiple tasks simultaneously.
