There is a section to the terms which says "Award criteria" and I guess that means you can only take part if you meet that criteria, which is "Education and relevant work experience (40%) and Proven track-record of
creative work (60%)"
There is also a round of "public feedback" but not before it's been reviewed by a 20-strong jury of designers and professors from across Europe.
It feels a little belittling to call it a "design contest".
