> as we felt he might have trouble being managed by people significantly older than him

You didn't hire him because of his age. Isn't that illegal in pretty much the entire western world?

[Insanity]

It probably is. But, given a reason as "not being a good cultural fit" does not have to describe that it is about age I presume.

I guess that you can always make up some kind of excuse other than just saying "too old". But I am unaware of how they corresponded this to the person in question.

[basseq]

It's hard to understand whether this was a concern backed by data (observation), or general discrimination.

The former is legitimate: "this person will have issues with management and cause problems". The reason for this is a moot point: the candidate has issues with younger people, the candidate has a chip on his or her shoulder, or some other reason.

The latter is questionable: "This person is old, and old people have issues working for younger people, so we won't hire him."
