Here is all what the director seems to have said about the age limit (that is the same in the French school):

"I noticed in the past that we should not encourage too much age difference because it's harder then to form groups that work." (http://www.clubic.com/pro/emploi-informatique.clubic.com/act...)

"42 indeed focuses first on the 18-30. We think about other people with care, but we already initially have much to do." (http://www.vousnousils.fr/2013/04/12/nicolas-sadirac-l%E2%80...)

Regarding this statement -

"I noticed in the past that we should not encourage too much age difference because it's harder then to form groups that work."

Shouldn't a startup founder be then allowed to reject any 30+ candidate with the same reasoning if their company already has a bunch of 25 year olds? Can't you detect the blatant age bias in this statement?

I can. It may be relevant to mention there must be a couple of cultural differences on this point. I think most people in France may have never heard about the word "ageism", from the moment they're not in some social justice circles. Employment discrimination is a public sphere topic but it is much more about immigrants and women. Also, the tech labor market in SF bay area may display way different variables compared to Paris (as may the educational system).
