Jos, if you write oversimplifications like these ones, you really make it seems you just have an agenda of promoting openSUSE's recruitment system!
As I suspect that was not your intention, I suggest bringing a bit more depth to the discussion.
It is indisputable that "quizzes" (an actual misnomer, as written in the article) and similar joining process tend to be more bureaucratic, one should investigate what are the reasons behind them. For instance, in the case of Debian, the reasons are quite profound and have been covered by an interesting paper by Biella Coleman, called "three ethical moments in Debian" (see e.g. https://lwn.net/Articles/149031/ ).
While you can get rid of most "quizzes" to verify technical abilities (like we've done in Debian, as observer by Ben Hutchings in the comments here), verifying alignment of visions and principles is a tad more tricky.
