This overstates the situation.

Shopify’s official internships site shows that the company already ran Engineering & Data Internships, with named intern roles and a defined hiring process (apply, assessments, interviews, decision). That contradicts the blanket claim that Shopify had "no internship opportunities open".

Julia Fedorin’s own follow-up post describes the opportunity more narrowly: she says Shopify "doesn't typically hire non-technical interns" and thanked the team for "making space for a role that didn't exist—until now." In other words, the unusual part was the creation of a marketing/non-technical internship for her, not the absence of internships at Shopify altogether.

So the article’s wording is too broad: Shopify had internship opportunities; Julia appears to have created a new kind of one.
