A dated record of the job postings that had been listed longest that week, as measured at the time. Ranked across all countries we track, not US-only.
Each row links to the posting behind its age, on the employer’s own board. Ages are counted from the date that board published. Where a board published no date, the age is a minimum counted from when we first saw the posting and is marked +; where we hold no age at all, the row says so rather than estimating one.
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 stay listed for many legitimate reasons — for example, evergreen requisitions, high-volume or continuous hiring, backfills, or slow internal processes. These are counts and durations only.
