People in the US don't put their age on their resume, and many people past a certain age try to obscure data on the resume that would give their age away. It's illegal to ask in an interview, so perhaps they didn't realize until they saw the candidate in person. I remember reading somewhere the average age of google employees (that's all employees, not new hires) is below 30. A group like that isn't likely to hire someone too old for them to relate to any more than a company with an average age over 50 is going to be interested in hiring a 19 yr old. We can't relate to people of a different age, that's the way it's always been. Where I live, if your date of birth (and in some cases recent color photograph) isn't on your resume, they'll assume you have something to hide and you'll get no response. Might as well be upfront about it.
