How on earth am I, a potential job seeker, supposed to be able to figure out if your year-old job posting is still up because you: couldn't find anyone after a year, are constantly hiring and never take it down, actually hired your quota six months ago and HR forgot to take the listing down, the job listing isn't for a real job and is just a trap to collect resumes, the listing is for a ghost job to placate the overworked current staff, some other reason?
