How we know

It hasn't been reposted, listed twice, or left up unusually long, and the posting doesn't say it's a talent pool.

Ghostless records the day it first sees a posting, so a repost can't reset its age. This one was already up when Ghostless started tracking Singlequantum.jobs.personio.com, so its true age is longer.

Last checked Nov 1, 2026.

Not stated: Pay, real vacancy, AI screening.
