To apply, you must be at least 21, because there is certainly drinking involved in the gig. What else would you expect? You'll also attend events as a brand ambassador, create content for social channels, do product research ("yes, it's what you think it is"), design swag, and manage a vlog that documents your internship.
It is a paid internship, though the listing doesn't specify what you'll be getting. However, a representative tells Thrillist that "the amount equates to an annual starting salary of $83,200 or roughly $40 an hour." Though, you won't be working for a full year. The representative said that the eight-week period's salary would have an "approximate retail value" of $12,800. That's, like, enough to buy 12,800 cans of Natural Light.
