It's not stated or implied that such candidates were considered unfit to hire, merely less-than-ideal - I took it as an indication that in this place, pretty much all applications are from less-than-ideal candidates, some of which turn out to be very promising (Gloria), while others are impolite and entitled, or don't even show up.

As I read the story, "Dads Resume" was a specific candidate, so named because that was evidently the filename of the email attachment.

That said, there was at least one explicit age reference fairly early on. It put me on edge. But not a lot more was made of it in the article, and I had some sense that a fair number of the candidates invited for interviews were at least middle-aged.

While there was an age reference for the "Dad’s Resume" guy, that applicant was not rejected on age, instead he was asked in for an interview.

"Dad" was reject because: "The last guy was 15 minutes late, full of himself, and he wants the moon. I’m not asking him back."

'Dads Resume' is called like that because apparently he can't even type up a resume on a computer, a skill that is right down there under 'assumed to know, not even listed on the job requirements' along with 'tying own shoes' and 'not forgetting to breath'.
