I do ask this question in a initial questionnaire. I list bunch of technologies and just require this input. I do agree with all the points in the article, but my goal is to have relative scale. I am not able to verify all the needed technologies, but I can do verify few. Whatever the scale candidate choose, I assume its consistent. If someone self-scores 9/10 out of Postgres and doesn't understand basic things, I can safely assume his other 9/10 are worthless.

Agreed, it's a bozo filter. It's not intended to find good candidates, it's intended to weed out bad ones.
