Read straight from Horizon3's careers page (ashby). Each company's careers page is read about once an hour. Posting dates come from the company's own applicant tracking system, not from when ReqHunt first saw the role. “No longer listed” means the role has left the company's careers feed. That can mean filled, cancelled or withdrawn — the feed does not say which.
