I once worked for a company that needed a technical buyer, so they advertised internal/externally and then boss (middle manager) decided to employ his new wife instead.
The original role was for a technical assessor/project manager with purchasing experience but since the wife was getting the job it became just a purchasing clerk with zero technical expertise required.
On linkedIn she posts that she did the original job specification when her only real skill was operating a till in a small shop and allowing her boss, who was already married with kids at the time, to bend her over the counter.
Same boss employs an Exchange Administrator, job requirements are full knowledge of exchange, protocoles, DNS, networking etc, he employs a typist instead with zero technical knowledge who is again female.
All three are on LinkedIn and all of them claim to have technical knowledge/ability with each BS'er supporting the others, one gets a job and then the rest follow until they are found out then repeat.
To me, LinkedIn is exaggerated CV information gone wild and I would not believe a word I read on there, those real professional who still use the service are both validating it and being tarred with the same brush as the BS'ers so get out before it is too late.
