Social media company Facebook offers America’s best-paying internships, according to a new survey by Glassdoor, while energy giant ExxonMobil is the only oil and gas company represented in the top 10.

Tech companies dominated the salary website’s ranking of the 25 most lucrative internships, taking eight of the top 10 spots. Leading the pack are the lucky few who land an internship at Facebook, who will be pulling in $8,000 a month.

The highest-paying non-tech company on the list was ExxonMobil, which came in third with a median monthly paycheck of $6,507. A former intern praised the oil company for its focus on professional development and management style.

Chevron was the only other energy company to make the list, coming in at number 21.

To compile the list, Glassdoor reviewed companies that had at least 25 median monthly salary reports for US-based interns from April 2016 to April 2017, according to Bloomberg. The study generally echoed a survey of Silicon Valley interns conducted last year.

The US national average wage is $48,098, or about $4,000 a month – half the salary of a Facebook intern.
