Worst offenders

Methodology: roles are counted from each company's own job board and dated by the posting date that board publishes, then checked daily. A “N+ days” duration means the board doesn't publish an exact post date, so the age shown is a minimum. Postings can remain open for many legitimate reasons — for example, evergreen requisitions, high-volume or continuous hiring, backfills, or slow internal processes. These are counts and durations only.
