It is often difficult for older job seekers to get interviews. A recent study by the Federal Reserve Bank of San Francisco that sent out fictitious resumes to job postings found that older applicants received the fewest interview requests.

"If you list your high school graduation year, they can get within a couple of years of your age," says David Neumark, an economics professor at the University of California, Irvine, and co-author of the report. "It's not clear you should hide your age, but it's not crazy, either."
