According to the leading job website, Glassdoor's annual "100 Best Places to Work in the US" list that came out on Wednesday, Boston-based management consulting firm Bain & Co. has been ranked No 1.
Facebook is now ranked No 7 -- scoring 4.5 out of a perfect 5.
Amazon didn't even make it to the list, with an award score of 4.1, just outside of the top 100.
Apple, on the other hand, moved up in the ranking, from No. 84 to 71, though it maintained the same score of 4.3. Microsoft moved up in ranking from No. 39 to 34 on the list although their award score dropped from 4.4 to 4.3. Google was 8th while Salesforce came 11th.
The Glassdoor list came at a time when media reports said several Facebook employees are looking for better opportunities as scrutiny of the company's conduct rises following several cases of data leak and as its stock price take a beating.
According to a report in the Wall Street Journal, last month citing an internal survey at Facebook, just over half of Facebook employees (52 per cent) said they were optimistic about the future of the social networking platform -- down by 32 per cent last year.
According to the report, Facebook's "difficult year is taking a toll on employee morale, with several key measures of internal sentiment taking a sharp turn for the worse over the past year".
Facebook investors have increased pressure on Chairman and CEO Mark Zuckerberg to step down after a New York Times investigation suggested that the social network hired a Republican-owned political consulting and PR firm that "dug up dirt on its competitors".
Zuckerberg, however, has refused to quit.
