Are jobs removed once they are filled?

We try our best to only post jobs that are still available. We remove job listings after (1) 30 days since the date posted (2) an employer tells us they filled the position (be it by phone, email, or in person) (3) an employer removes the listing directly. We also send weekly surveys to employers asking if they are still hiring. If we learn they are not, we remove the job post. As we said, we try our best!
