Tim Cook, Apple
Apple's reviewers on Glassdoor worried that Cook might have lost some of the commitment to the experience of the customer and employee since Steve Jobs passed away in 2011. Despite that, Cook still pulled in a 92 percent approval rating. Employees said that there was often little direction from management, but some employees saw that as a way to excel in a tough environment.
"You cannot look for success at Apple, you must create success at Apple. If you apply for any position that you think you would feel comfortable in, know that it will push you through many obstacles that are out of your comfort zone," one reviewer wrote.
