As someone over 55 that went 9 months looking for a job I can say they do not have to “see” you to determine your age. When you have not jumped jobs during your career thus having only a few to list they can do the math from your resume.

I’ve worked only 3 places my entire life, due to staying put like they did in the old days.

Never would have dreamed that would be some sort of negative.

My father, who was a very proud, self-sufficient person - was laid-off at the age of 52, from the one company he worked for from the time he left the Navy. He and mom still had a couple teenagers at home, and he had never not-worked his entire life (often had two jobs), so the inability to find work was a big psychological hit. It was the early 1980s, so times were bad for everywhere - and especially for older workers.

He was always a very loyal company-man, but from that experience he told me constantly: Develop yourself and career to gain your own independence and freedom. You can’t trust a company, the promises of government, or anyone else to provide for you and your family.

You don't HAVE To list all the jobs you have had. Going back ten years is enough. They will figure it out if you list the date of receiving your college degree, though.
