Managing directors, also known as chief executives, control the day-to-day operations of a company and are responsible for its performance. They carry out the strategy set by the chairperson and board of directors. Most industries employ managing directors; publicly traded companies tend to hire the most. Managing directors work in corporate offices. The amount of hours they work depends on their industry, as industries such as finance and accounting have busy seasons that may involve 70- or 80-hour work weeks. Decision makers, managing directors are comfortable taking responsibility for their decisions and thrive in a high-pressure environment.
