That's very hard to believe. What companies have you seen that at?
Plenty even studied physics or something similar instead of computer science and then got job in company desperate for people on the basis of "you are smart so we guess you will be able to learn". Actually turned out that if you have brain for physics or math, you can learn programming reasonably fast too. (And ended up being better then weak cs students.)
They would not be suitable for all companies and positions obviously, but grasping enough of basics so you can be useful enough to create part of frontend pages/load data from db/whatever with a bit of supervision is not that hard.
