A few years ago, my daughter applied for a job with a local business as a FT copywriter. In the interview, she was duly quizzed... about me, my career, my salary and only then did they move onto asking about her work experience (none, other than what she'd studied in a module during her degree - up until then, she'd worked in restaurants, PT). Because the business was local, I shrugged my shoulders and thought perhaps the business owner thought he knew me somehow (he didn't) given our unusual surname.
My daughter was offered, and accepted the job. For perhaps three weeks she raved about how great the office was, how much she loved the campaign she'd immediately been given to work on/help launch... and then? As soon as the campaign had launched? She was "let go", and because she was still on probation, they refused to tell her why.
In hindsight, the business owner was truly a CF who was looking to use young, inexperienced graduates to get the grunt work his FT long-term, experienced employees either didn't want to, or perhaps couldn't, do themselves. In hindsight, he'd quizzed my daughter about me because he was looking for someone who had family support financially (she still lived at home, then) so that he could exploit the loopholes in probation for his own end.
The business went under less than a year after my daughter had worked there. No idea why, but I did smile a little more than usual on the day I found out the owner had lost his little company (whilst feeling sorry for the long-term employees). My daughter? Secured another position with a slightly better company within a month, fortunately and has been in steady employment pretty much ever since.
But parents of young graduates, beware! There are CF's like my daughter's former boss out there who will cheerfully exploit them for a pittance... then get rid as soon as they've got what they wanted from them!
