What do you mean by trash? Could you give an example?
Sometimes if they made it far enough, I'd sit with them at a computer and ask them to do something fairly simple, but something they most likely hadn't done before, so they need to figure out how to... then watch how the interact with the IDE, how they figure out how to do something (they can use the internet, any tools, ask me, etc). And most of the time, they just fall flat on their face.
I am also very business-minded having run my own outsource programming service overseas for the better part of a decade until I moved back to the USA 20 months ago.
Unfortunately I have learned that most companies in the USA these days are not willing to allow me to use the language in which I have developed and practiced my expertise for the past 15 years, regardless of how much faster I can produce for them in this language.
Instead most companies seen to hold out for programmers who know today's "popular" languages. So they lose out on my extensive background and experience, and I lose out on an opportunity to bring one of these companies the kind of service and performance they complain about not being able to find.
