much of our QA team in a us bases SaaS company were barely literate, some of them, however could turn a computer on.
some were promoted from customer service, other were "rock stars" hired on to compliment the team ( the previously mentioned barely literate ones) There we possible 2 or 3 longer term QA people who were brilliant, the rest ran scripts and signed off, so when production day came and the entire platform went to hades in a cornucopia with real world users, it was IT operations ( our team) who were blamed.
i had a moment of weakness once and looked into joining the QA team ( they got better perks then us mere tech-monkies bashing servers with hammers and such) but was told we were not smart enough and it needed specific skills and knowledge of the (in house built) platform (which we had extensive experience with having to actually support it and deploy it, but, whatever)
i used to make a point to the department heads thereafter about all the hairbrained tickets we used to get from their crack team of experts.
probably why i no longer work there, i would't say i burned my bridges so much as carpet bombed my whole career with the company.
but that's water under the (definitely destroyed and washed away) bridge now.
