Duplicate job listings now get caught after each run: the first dedupe compares only one day's listings on exact company and title, so a job that came back under a longer employer name, or with "Remote" or "with Security Clearance" added to its title, looked new.
The new step checks the whole history, and a copy takes on the earlier listing's mark, so a job already skipped or applied to doesn't return as new.
Two recruiters posting one client's job fold too, when a long stretch of their descriptions is word for word the same.
"Senior" and "Lead" still count as different jobs. A dry run was reviewed pair by pair before it went live, which caught same-title federal jobs at different agencies being matched; agency names are now guarded.
