I totally agree. The whole point of the post was to point out that there are lots of good coders out there that are being labeled as bad coders because of poor hiring processes.
When you spend an entire interview doing college computer science quiz type questions, and none of it on process, code review, coding style, development philosophy, approach to testing, etc.... you end up selecting for people who are good test-takers, but may not be any good at writing maintainable code. Or debugging. Or troubleshooting production issues. etc... etc...
