Regarding Scotts original point we assume companies check competency of their staff but some certainly don't.
It's not just the NHS that has the occasional dud. I investigated the work of a contractor's engineer a few years back and as a result his company landed up saying "adios" to him.
The most valuable tool in getting to know what new staff are capable of is also an excellent training method; a long spell (months) of good old shadowing.
You get plenty of time to discuss technical matters and past experience while showing them the ropes. It works well here, but I doubt manufacturers have the time and money for much of that.
