It doesn’t matter whether you are young or old; discrimination against age in the workplace is illegal. However, employers and hiring managers are always on the look out for telltale signs that reveals your age. Your resume is the first point of contact with any future employer and could be the first giveaway, without even realising. Any mention of dates are not the only giveaway to your age, there are 3 more subtle but easily avoidable resume fails.
Email Address
The first emails arrived in our lives in the early 1990s and these initial addresses are easily distinguishable from today. Firstly if you are still using email hosts such as AOL or MSN, the hiring manager might suspect that you are fairly old-school. Secondly, if your email address includes numbers, for example stevejobs1960@, most employers can safely assume that this is your date of birth or graduation year.
The best practice is to create a Gmail account using a combination of your first and last name or initials, avoiding any numbers.
Years Of Experience
When writing resumes it is common to list your years of experience with a synopsis of your achievements and skills acquired. It is important to remember that the purpose of this section is to depict your relevant experience, not your age. There are several things to remember to avoid this pitfall. For example, if you have been working in the same industry for 20 something years and a new job opportunity requires 10 years experience, you won’t necessarily get more brownie points my mentioning so. A useful tweak is to say you have 10+ years experience, thus alluding to the fact you have more, but not giving away your age.
Also be careful of your previous work history. The hiring manager does not need to know you worked in KFC as a cashier when you were 18 y/o. Generally employers are only interested in the past 5-10 years of relevant experience. Everything else should be left out, unless it is hugely relevant, in which case list these, without dates, in a separate section called ‘Other Experience’.
Significant Dates 
Revealing the year you graduated is a dead giveaway and is utterly irrelevant on your resume. You only need to include what you degree(s) are and the institution your graduated at. Also any awards and certifications can be clue to your age. For example, old-school certificates such as Speed Typing 101 or Microsoft Word & Powerpoint proficiency will make you appear outdated and irrelevant.
These simple best practice tips are easy ways to ensure you are not subjected to age discrimination on your resume. Stick to these three fixes and shine out from the crowd regardless of your age.
