Facebook is paying high school interns the equivalent of almost $75,000 a year, according to jobs site Glassdoor.

The website, which is known for employer reviews, pay levels and interview questions, said interns at the US technology firm were given $6,213 (£3,629, €4,569) a month.

If the lucky workers had the same salary for a year, that would come to $74,556 a year – or $21,510 more than the average annual household pay packet in the US.

But the research, which used user submitted figures to the jobs site, found that software firm Palantir Technologies was the most generous employer by giving interns $7,012 a month.

Microsoft, another well-known technology brand, did not lag far behind Facebook by paying its interns $6,138 a month.

In addition, the study found that internet search company Google paid its work experience staff $5,969 a month.

But beyond the high salaries for interns, the Silicon Valley still has a gender and ethnic diversity problem.

Google, for example, admitted that the company was not where it "wanted to be when it comes to diversity".

"And it is hard to address these kinds of challenges if you're not prepared to discuss them openly, and with the facts," the technology giant said on a blog.

"All of our efforts, including going public with these numbers, are designed to help us recruit and develop the world's most talented and diverse people."

According to its own figures, only three in ten (30%) of Google employees across the globe are female.

In addition, the firm also revealed that more than six in ten (61%) of its workers based in the US were white.
