14 firms are open for data and AI summer internships in London right now, each with its own portal, documents and deadline. Jorb AI's application agent handles the multi-firm workload in one place, tailoring a CV and cover letter for each role you pursue and tracking each application alongside the rest.
“Opened” is the date the firm posted a role, or the day Jorb AI first saw it on the firm’s own careers site, which we check daily. “No longer listed” means the posting has been gone for a few days. Last season’s dates are shown only for firms we were already following when that season began.
Open counts every listing still open, including those first seen before 1 June; Opened this season counts only those first seen since.
