I used to think like you.
But I'm 51 now. I've discovered that I was wrong.
The younger the technical interviewer, the less interested they are in my experience. I'm guessing that the less experience they have, the less value they see in experience. I suspect I was the same way 25 years ago.
I now understand why good developers go on to be lousy managers. They get old and get pushed out of development. Mid-level management is all that's available to them.
Fortunately I still have a job in an older development group. I still have some value, for now.
