No, these are two different sources with distinct purposes: [1]
"Find jobs" (Companies, People, Jobs) - This is our native source that lets you search for job openings across all companies or within specific company lists. You can filter by job titles, location, and job type. [2]
"Find jobs at these companies" - This appears to be an enrichment action that adds job data to an existing company list, rather than starting a job search from scratch.
The key difference: one is for discovering jobs as your starting point, the other enriches companies you already have with their job openings.
Thank you for reaching out to the support team. It seems that these are the same action. I appreciate you raising this and I'll pass this on internally as feedback to the product team.
