Ageism is probably not your greatest risk, scootie. To make it through the agent's clownshoe filter, you'll need a little luck. Perhaps some chewing gum will interpose itself between your CV and a credible one and then magically disperse later on. Once you reach the unfiltered pile, you're ready for the next stage where they submit all CVs to the client's hiring manager to pass the chuckle test. That stage might be harder for you.
