The myth that Indians are "smart"

I don't know who ever came up with this particular myth, but take it from me - I work with dozens of them every day and they are, as a general rule, at least as stupid and clueless as the rest of the population.

I'm currently marking a skills test I set for about 50 staff at my workplace who are relatively new with between four and six months of experience.  If you asked me to generalise their knowledge I'd say the lot of them are as thick as a pig shit sandwich, with the odd individual exception.

I'm actually getting quite depressed marking the answers, the degree of cluelessness being exhibited is really rather frightening, as they've all been trained - and have apparently failed to understand a lot of it.
