I leave that sort of thing to the "Professionals", Umish.

I have come across "contractors" working on hospital sites on medical device who have no practical experience of working on Medical Device, yet employed as a contractor.
OK ... let’s get to the bottom of this (even though it’s like drawing hens’ teeth):- are we talking about foreign agency workers, "pretend biomeds" (
wannabees), blokes who didn't impress you, (otherwise) experienced techs working on kit unfamiliar to them, competent blokes without "certificates of comfort", "educated idiots" with no practical
nous ... or what?
In my experience, agency jobs are few and far between these days, so it should be a "buyer’s market" ... unless, that is, *managers are looking for the cheapest possible guy. In that case, when "you pay peanuts, you get monkeys"!
* Or agents looking for the maximum possible margin (profit).
