The folks who work at Facebook apparently like – and recommend - where they work.

The fast-growing social networking site received the top ranking in Glassdoor.com’s third annual list of the top 50 Best Places to Work.

Mark Zuckerberg, Facebook’s chief executive, received a 96 percent approval rating from employees who reviewed the company. Zuckerberg was named Time Magazine's Person of the Year on Wednesday.

The rankings are based on an anonymous survey that employees submit about their employers on Glassdoor.com’s website. The company also gathers employee reviews, information about employer salaries, the interview process and jobs that are available.

Glassdoor.com officials say they review all submissions to make sure they aren’t fraudulent or an attempt to juice a company’s numbers, and they toss about 15 percent of them.

Facebook wasn’t even on Glassdoor.com’s list last year. This year, however, it beat out reigning champ Southwest Airlines, which dropped to No. 2.

The other companies in the top five are consulting firm Bain & Co., food producer General Mills and public relations firm Edelman.
