Sounds like you don't phone screen.

I've screened people like you describe, but the only time I've interviewed them face-to-face was when they didn't have a technical phone screen for whatever reason.

FWIW, one of the ways I screen companies when I'm looking is whiteboard problems. I refuse them and move on. In my experience, only HugeCos and places with problems use them. I'm sure that's not true, but I have a necessarily small sample-size, and skipping over firms that do it has worked well for me so far, and there are plenty of fish in the sea. (I do in fact suck at writing on whiteboards, I just don't consider it a skill worth developing to pursue jobs I probably don't want.)
