"To help people find companies that stand out from the pack, the Glassdoor Employees' Choice Awards recognize employers that are truly Best Places to Work because they're determined by those who really know best - the employees", said Robert Hohman, CEO and co-founder of Glassdoor.
To be fair, Apple remains a highly rated employer, with a 4.3 out of 5 rating at the time Glassdoor compiled the list - a rating that inched up slightly by 0.1 versus a year ago.
Glassdoor shared employee reviews of Facebook, and the reviews from three employees heaped praise on the general work culture, which they described as offering plenty of opportunities, excellent benefits, interesting and innovative environments, fantastic leaders and good rewards.
However, this is the first time that Facebook has featured first top of the list since 2013, showing an improvement since slipping to 13th in 2015.
However, for individuals who may not have the right skill-set to work at Facebook, there are a set of 40 new companies on Glassdoor's list this year, such as Blizzard Entertainment and T-Mobile. "We are thrilled with this award because it comes from real employees' reviews and authentic feedback", said Sheryl Sandberg, Facebook Chief Operating Officer. "We all believe in what we are doing and and we value our relationships with others".
All these benefits are certainly contributing factors as to why one of the world's most profitable companies is listed as a great place to work, hitting number 1 out of 100 companies on the list.
Google featured 5th on the U.S. list, whilst Apple slipped to a much worse 84th place.
