Agree with FE.But when I was made redundant at 55yrsmy cv had my D.o.b. at the top of the page, I was getting few responsess so I moved it to the end of the CV and coincidence perhaps but I obtained a higher reponse rate and eventually suitable employment.
I applied for over 30 positions with my DOB on my CV. I took it off and got the first job I applied for.
Might be a coincidence, it might not, I don't know.
If you are good enough for the job it should not make any difference how old you are. I do believe though that you get a lot of young staff at employment agencies with an attitude of ageism illegal or not.
