Postings rarely close. Almost none of this company's roles have ever come down, and the open ones have been up a long time. Could be steady backfill — or low fill-rate. Worth extra scrutiny before you invest hours. (Posting-age is measured from the company's own post date; "time-to-close" is the window we observed each role stay live.)
