It depends on the person, obviously. But, I hope you sprinkle in a few of those types of analysis questions in your standardized interviews so that older people like me even have a chance.
It hurts (both emotionally and financially) to be rejected by younger teams because they assume things about me that aren't true. I now get the dreaded "has too much experience and would be bored" rejection line all too often.
There is only one way to go there. Start a consultancy and be your own boss. That is about it for us older folks. Most of your customers don't want stellar code: they want you to fix what is broken (which is simple enough).
