We never post fake jobs
This isnt a trick. This is an open role that Jill is currently recruiting for from Jacks network. Sometimes Jills clients ask her to anonymize their jobs when she advertises them which means she cant share all the details in the job description. We appreciate this can make them look a bit suspect but there isnt much we can do about it.

Give Jack a spin! You could land this role. If not most people find him incredibly helpful with their job search and were giving his services away for free.
