Specific positions might require you to submit a more thorough CV, such as jobs in academia or management positions. Having plenty of professional experience that goes over more than 10 years can prove that you are qualified for a high-level position without the recruiter going over your CV in detail.
Drawbacks to a CV that includes older jobs include possible age discrimination issues. Younger candidates who might not have the same experience as you might land the job instead simply due to their youth. Age discrimination is prevalent in many industries and affects those 64 to 66 years old more so than other age groups, according to the U.S. Bureau of Labor Statistics. A lengthy work history section also runs the risk of creating a CV that’s more than two pages long; employers generally lose patience with CV of that length.
