This management-consulting powerhouse works with companies in 30 different industries, giving MBAs exposure to a broad variety of fields.

In addition to the skills gained working at McKinsey, employees become part of a 30,000-person alumni network -- including big name former employees like Facebook COO Sheryl Sandberg and Morgan Stanley CEO James Gorman -- spanning dozens of industries across the globe. "A McKinsey network can be the best career tool a person can have," says director of global recruiting, Brian Rolfes.

What they're looking for: Hiring managers are looking for workers with the ability to solve problems and work with a team as well as proven leadership experience, Rolfes says. "An entrepreneurial spirit is a huge positive for candidates and a common part of McKinsey's culture."
