That’s a fair question, but I’ve seen companies I’ve worked for and thought were good repeatedly posting ads until they filled a position. The hiring manager could be overambitious or under pressure, and also that school is in a somewhat remote area.
What, I think, is more telling is the fact that I’m reaching a point of desperation as the school year approaches, I’ve yet to find a job, and I’m picking over what’s left. I’m waiting to see what recruiters come up with, but I need to have options, even if they are bad ones.
I have also seen schools described as bad post one ad, and not repost it.
