Four years ago I wrote a blog post titled The Skinny on Fake Job Postings. Read the short post, the comments, and the original article I referenced.
Fake job postings are a disgrace, and a slap in our face. They contribute to the frustration of job seekers. The postings are there because companies/people will pay for them, and those companies/people can get good information.
As long as money changes hands I’m not sure there is anything we can do, but please look for warning signals, and stay safe!
