Similar in my previous job. Company (flooring manufacturer) took on a customer services assistant who bigged up in her interview and CV that she actually had an Interior Design degree.
As a member of the design team, I was naturally interested in where she studied. She refused to speak to me about it, which I thought was odd. I smelled a rat, in fact.
Management however, decided that she was wonderful and it was a waste to ask her to just answer phones and process orders, so gave her the entire head office building to redesign the floors for. Cue me being handed a pile of scrappy sketches, hand-coloured in, with wax kiddy crayons of multiple rooms to do proper layouts for, so the new floors could be manufactured and installed.
I asked her what scale her sketches were in, so I could adjust sizes to fit the materials used and quantify requirements, and she looked at me like I'd asked her to explain quantum dynamics in Mandarin Chinese.
Turns out there was no degree, there was no college attendence and management were pissed off at ME for it for raising it right at the start and them ignoring my suggestion that it was fantasy on her part.
She was crap at order processing too, and got fired 6 months later.
